EDITING AND SAVING 6 This chapter explains how to define functions, how to edit them, and how to save your work. Defining Functions(FUNCTIONS NIL Functions NIL NIL 1 SUBNAME DEFINING SUBTEXT defining) 1 DEFUN(DEFUN (Function) NIL NIL NIL 1) can be used to define new functions. The syntax for it is: (DEFUN ( (

)) New functions can be created with DEFUN by typing directly into the Executive Window. Once defined, a function is a part of the Medley environment. For example, the function EXAMPLE-ADDER(EXAMPLE-ADDER (Function) NIL NIL NIL 1) is defined in Figure 7-1. `—‹ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÇúûÃ¿¿ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ»÷w½¿ßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ»û÷¯¿ßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ×vïçïß¿ïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿïÿûïß¿ïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿï~ÿûï¯¿ïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ×vï»ïw½¿ïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ»ÇöûÃßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ÷ÿÿÿßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿûÿÿÿ¿ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ000€Á€€0À00 €0000Á€À00 €`pG€1óÏ³|ÌÎ=çÌð‡Ïž|àÏ38÷Ÿ3À}›ãÏ³Ï€gÏ·Ï€ˆH¢@c6f3fgƒ36m™ðÌÙ³l03žÌÙ¶`1›6f6lÀÆm¶f0€Œ c7æ3fã36mùóÌÙ¿`00Œ<ÌÙ·à1›66lÀÆl6f c63f36m€ÌÙ°`600lÌÙ¶1›66lÀÆl6f‰" c6f3fg›36m˜ÌÙ³`603žlÌÙ¶`1›6f6lÀÆl6frœ@aóÆfÌÏ³7ÌðçÏž`à3>Ìß3À0û3Ã³ÌÀÇÌ6c€€0f0f€06Ûö€€Ì`a€ØÆÆc€ÆÀ0ÀØÇÇ€{7¼Ï÷Ç€ûçÏæoyñçÏ<ÆÁ€8À<0ÀÆlÀË6ffÆlÀc6Ù³6lÍ›6Ùd€`f`ÆoÀã6ffÆoÀc6¿6lÍ›öp‡à<```Æl;6ffÆlc606lÍ›‡àl```ÆlÀ›6ffÆlÀc6³6lÍ›6L€l`f`Æg€ñöfÆvg€;63ìÍñæx€>À<`À0ÀÀ0À`a€ù„O>!ãÇÏFÈ Q$€€¡FÈ Q$€ðAEH<Q'€B%O |‰$ €£åH ù$ %H ‰$€ù$H>‰ãÇÈ€pG€ˆH¸@0ƒ ˆ‰ˆ r@€ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ Figure 7-1.

Using FIX to Edit a Fundion Move the text cursor to the appropriate place in the function by positioning the mouse cursor and pressing the left mouse button. Delete text by moving the caret to the beginning of the section to be deleted. Hold the right mouse button down and move the mouse cursor over the text. All of the highlighted text between the caret and mouse cursor is deleted when you release the right mouse button. If you make a mistake, deletions can be undone. Press the UNDO key on the keypad to the left of the keyboard. Now change GREATER to BIGGER: 1. Position the mouse cursor on the G of GREATER, and click the left mouse button. The text cursor is now where the mouse cursor is. 2. Next, press the right mouse button and hold it down. Notice that if you move the mouse cursor around, it will blacken the characters from the text cursor to the mouse cursor. Move the mouse so that the word "GREATER" is highlighted. 3. Release the right mouse button and GREATER is deleted. 4. Without moving the cursor, type in BIGGER. 5. There are two ways to end the editing session and run the function. One is to type Control-X. (Hold the Control key down, and type X.) Another is to move the text cursor to the end of the line and crù In both cases, the function has been edited! Try the new version of the function by typing: 3/48> (YOUR-FIRST-FUNCTION 8 9) (THE SECOND IS BIGGER) and get the new result, or you can type: 3/49> REDO 42 (THE SECOND IS BIGGER) Using the List Structure Editor 1 If the function you want to edit is not readily available (i.e. the function is not in the Executive Window, and you can't remember the history list number, or you simply have a lot of editing), use the List Structure Editor(LIST% STRUCTURE% EDITOR NIL List% Structure% Editor NIL NIL 3), often called SEdit. This editor is evoked with a call to ED: 81¬(ED 'YOUR-FIRST-FUNCTION 'FUNCTIONS) Your function will be displayed in an edit window, as in Figure 7-5. If there is no edit window on the screen, you will be prompted to create a window. As before, hold the leff mouse button down, move the mouse until it forms a rectangle of an acceptable size and shape, then release the button. Your function definition will automatically appear in this edit window. `VŠ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ0À0À0À0À0À0À0À0À0À0À0À0À0À0À0À0À0À?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ?ÿÿÿ¿ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ?ý·ï¼=öð;ÁÀ| öûÃ€Þûüÿ÷ÿÿÿÿ}áßý÷ÿÿÀ>ûý÷÷{Ýöû÷û}¾ûýýö{½÷Ýî{ýïÿ÷ÿÿÿÿ»Þßýöû¾ÿÿÀ>ÿÅ¡÷wíöû÷û}¿ûýýö»÷Ûö»ýîû¹·ýûÝöû÷û}¾ûýýöó½÷ÝîóýýÛ·nÜÝÿ»Þßýöû¾ÿÿÀ?Å¹ýü>û÷û}ÁûýþûÃ÷Þûýþ,w±bã¿}áÀþ¾ÿÿÀ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÞÿ¿ÿÿÿÿÿÿÿÿÿÿÀ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿáÿÿÿÿÿÿÿÿÿÿÿÿÀ?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÀ0À0À0À0À0À0À0#ó÷ìn0G<øãÃ€>Dˆãã‡ À0#o0H‘"€B$B DÉ™PAÀ0Co0ˆ‘"€B$B DÉ™ P@€À0CçÌm°ˆ‘<ðCÃDøÇÇ"xáÀ>ùóÁÀ0D€$‘2DB ‘ (!!À0D€$‘2DB ‘ (!

An Edit Window Many changes are easily done with the structure editor. Notice that by pressing the left mouse button you can place the caret in position, and by pressing the middle mouse button you can select atoms or s-expressions. Repeated pressing of the middle button selects bigger pieces of text. To add an expression that does not appear in the edit window (i.e., it cannot simply be underlined), place the caret at the insertion point and type it in..

Placement of Comments There are other editor commands which can be very useful. To learn about them, read Appendix B of the Release Notes. File Functions and Variables: How to See and Save Them 1 With Medley, all work is done inside the Lisp environment. There is no operating system or command level other than the Executive Window. All functions and data structures are defined and edited using normal Lisp commands. This sertion describes tools in the Medley environment that will keep track of any changes that you make in the environment that you have not yet saved on files, such as defining new functions, changing the values of variables, or adding new variables. And it then has you save the changes in a file you specify. All of these functions are in the INTERLISP (IL:) package. File Variables(FILE% VARIABLES NIL File% Variables NIL NIL 5) 1 Certain system-defined global variables are used by the file package to keep track of the environment as it stands. You can get system information by checking the values of these variables. Two important variables follow. ÿÿïfÿ FILELST evaluates to a list, all files that yoU have loaded into the Medley environment. ÿÿïfÿ filenameCOMS (Each file loaded into the Lisp environment has associated with it a global variable, whose name is formed by appending COMS to the end of the filename.) This variable evaluates to a list of all the functions, variables, bitmaps, windows, and soon, that are stored on that particular file. For example, if you type: MYFILECOMS the system will respond with something like: ((FNS YOUR-FIRST-FUNCTION ) VARS)) Saving Interlisp-D on Files 1 The functions (FILES?) and (MAKEFILE 'filename) are useful when it is time to save function, variables, windows, bitmaps, records and whatever else to files. (FILES?) displays a list of variables that have values and are not already a part of any file, and then the functions that are not already part of any file. Type: (FILES?) the system will respond with something like: the variables: MY.VARIABLE CURRENT.TURTLE...to be dumped the functions: RIGHT LEFT FORWARD BACKWARD CLEAR-SCREEN...to be dumped want to say where the above go? If you type Y, the system will prompt with each item. There are three options: 1. To save the item, type the filename (unquoted) of the file where the item should be placed. (This can be a brand new file or an existing file.) 2. To skip the item, without removing it from consideration the next time (FILES?) is called, type crù This will allow you to postpone the decision about where to save the item. 3. If the item should not be saved at all, type ]. Nowhere will appear after the item. Part of an example interaction is shown in the following figure: ffÉÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€øÿÿÿí¾À@`wûƒƒ¿ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ûÿÿÿÿÝžûßï·û}½ßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ûýÜxÿÝ®ûßï·û½ßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ø»·½¶ûÀï·û‡½ïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ûÿx7ÿ½¶ûßàwûûƒïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ûÿ{÷ÿ½ºûßï·ûý¿ïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ûþ»·½¼ûßï·û}¿ïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ø ÜxÿÝ¾ûÀo°;ƒ¿ßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ÿÿÿÿÿßÿÿÿÿÿÿÿÿßÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ÿÿÿÿÿïÿÿÿÿÿÿÿÿ¿ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À¿lž0€À0l33€Çß0l83€Ä >l€Ç„|0l€ÀH 0l€ÄH0l3€Ãˆ0oß¾€À€À€À€0€À€À€ÇÀ €Á €Á,8Ò&Ë€Á€2D2%L‘&€Á€"|%HŸ"€Á€"@%H"€Á€2D2eL‘&€Á,8Ñ¥K€À€À€À€À€À€ÄO‘>8ð@‡‡Dùãˆ8ˆà€ÆH @DH€d"DÙ€ÆH Xqa£‡<8DH„dR"DÙ€ÅO<à"d ’dH€D¡G†TñSÁ D¨À€ÅH Dy'ÆD¢%TR D¨ €ÄÈ D‰$D£äˆ€L€¢"D©€ÄÈ "D‰dH€DB$H„L€¢"D©€ÄOŠ 8ùðDy£‡8B$GDø¢Ÿ8ˆà€À €ÀÀ€À€À€À€Àò#€>|qð€À$@@ˆ@€À$B@ˆ@€Àâ£x`@€À €@@€Àd@@ˆ@€ÀdB@ˆ@€À#‚|p@€À€À€À€À€À€Àpp@ˆÀ€Àˆ@€Ø" €ÀXÀˆãfÇ@pâÀ,Dqâ%‡Ù'‹x€Àd "¥H™@ ˆ2Dˆ‚&H‘©‚‘" €ÀD€>¥H‘@Â D€‚$Œ©B €ÀD@ ‰¥H‘@" D€‚$¨¢" €Àd2 ‘"‰¥H‘@ ‰ Lˆ’d‘¨¢"H"$€ÀXÑÀpâ¥G|âÀ 4pa¤ˆAÁˆ €À@@€À@€€À€À€À€Àp8À€À@ €ÀXÀñÃXp@–xpâÀ€Àd "A$D"dˆ@ˆ™" €ÀD€>A$"D`‘ €ÀD@ A$"D‘ €Àd2 ‘"A2$D‚"Dˆ@ ‘"$ €ÀXÑÀ@Ò#ƒDp@‘â €À@€À@€À€À€À€À€ À€À@€ €ÄG<ðà‡D°âÃ€,8âÃˆŽ4p Ž€Ä@™A@‘DÉ$@2D$H‘Lˆ@‘"€ÅG‘A‘T‰òÀ"|ò$EDˆ€Ÿ€ÅH‘AˆŠT‰"@$EDˆ€Âˆ‘IHŠ(‰@ "D$BLˆ€"€Â‡‘0à‡„(ˆâ€"8òÃ‚4p€€À€À8€À€À€À€€Á€€Á€€€€ÂŽ6lq`,qâÄG"Xpà@€Â*T‰2ˆƒ$Hˆ"d‰@€Â*T‰"`‚H"@øÀ@€Â‘*T‰"‚H"@€ @€Â‘*T‰2ˆ’È‰&@‰@€Á*TqÁ,pbG@pà€€Á €€À€ €À€À€À€Ä@€€ÆÀ€€ÆÈ‘|@€À€À€À€À€À€ÇÀ Ç>8qÈ‘|pâ#€>8p€Á ‘ ‰™"!$@ Dˆ€Á,8áÆË8h@‘ ‰™"!$@ Dˆ€Á€2D%L‚D˜@ˆž<Pˆ• !£8qpâ#‚ 8p€À€À€À€À€À€ÇÀ à@àƒˆŸ"ñÇŽDò$G8ˆàŽáÄO>xqóÄO€€Á A„"$H"d&H„DÉ"$H„ D‰$H€Á,8!ÃA„*$H"d&H„DÉ"$H„ D‰$H€Á€2D DD&A „*â' Tâ%HD¨À"$ODqò!€€À€€À €À€À€À€À€À€ÇÎ€Ä €ÇŽ|€ÀQ €ÄQ€ÃŽ€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€À€ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ€ Figure 7-9. Part of an interaction using the function FILES? (FILES?) assembles the items by adding them to the appropriate file's COMS variable (see the File Variables section above). (FILES?) does NOT write the file to secondary storage (disks or floppies). It only upclates the global variables discussed in the File Variables section above. (MAKEFILE 'filename) actually writes the file to secondary storage. Type: (MAKEFILE 'MY.FILE.NAME) and the system will create the file. The function returns the full name of the file created. (i.e. {DSK}MY.FlLE.NAME.; 1). Files written to (DSK) are permanent files. They can be removed only by the user deleting them or by reformatting the disk. Other file manipulation functions can be found in Chapter 4.(LIST ((PAGE NIL (PAPERSIZE Letter FOLIOINFO (ARABIC "7-" "") STARTINGPAGE# 1) (0 0 612 792) ((FOLIO NIL (PARALOOKS (QUAD RIGHT) CHARLOOKS (SUPERSCRIPT 0 INVISIBLE OFF SELECTPOINT OFF PROTECTED OFF SIZE 10 FAMILY HELVETICA OVERLINE OFF STRIKEOUT OFF UNDERLINE OFF EXPANSION REGULAR SLOPE REGULAR WEIGHT MEDIUM INVERTED OFF USERINFO NIL STYLE NIL) FORMATINFO (ARABIC "7-" "")) (270 15 288 36) NIL) (HEADING NIL (HEADINGTYPE FOOTINGR) (54 27 558 36) NIL) (TEXT NIL NIL (54 54 504 690) NIL))) (PAGE NIL (PAPERSIZE Letter FOLIOINFO (ARABIC "7-" "")) (0 0 612 792) ((FOLIO NIL (PARALOOKS (QUAD LEFT) CHARLOOKS (SUPERSCRIPT 0 INVISIBLE OFF SELECTPOINT OFF PROTECTED OFF SIZE 10 FAMILY HELVETICA OVERLINE OFF STRIKEOUT OFF UNDERLINE OFF EXPANSION REGULAR SLOPE REGULAR WEIGHT MEDIUM INVERTED OFF USERINFO NIL STYLE NIL) FORMATINFO (ARABIC "7-" "")) (54 15 288 36) NIL) (HEADING NIL (HEADINGTYPE FOOTINGV) (54 27 558 36) NIL) (HEADING NIL (HEADINGTYPE VERSOHEAD) (54 762 558 36) NIL) (TEXT NIL NIL (54 54 504 684) NIL))) (PAGE NIL (PAPERSIZE Letter FOLIOINFO (ARABIC "7-" "")) (0 0 612 792) ((FOLIO NIL (PARALOOKS (QUAD RIGHT) CHARLOOKS (SUPERSCRIPT 0 INVISIBLE OFF SELECTPOINT OFF PROTECTED OFF SIZE 10 FAMILY HELVETICA OVERLINE OFF STRIKEOUT OFF UNDERLINE OFF EXPANSION REGULAR SLOPE REGULAR WEIGHT MEDIUM INVERTED OFF USERINFO NIL STYLE NIL) FORMATINFO (ARABIC "7-" "")) (270 15 288 36) NIL) (HEADING NIL (HEADINGTYPE FOOTINGR) (54 27 558 36) NIL) (HEADING NIL (HEADINGTYPE RECTOHEAD) (54 762 558 36) NIL) (TEXT NIL NIL (54 54 504 684) NIL)))))!,llà2llà¢8HHà~¢8HHà~¢2llàT2llàT8Hà~¢8H¢à~¢8Hà~¨2HHàZ5Hà~2HHà Z2HHàZ2HZàZ8llà„œ´8llà„œ´2llà„,lHà2HTàT,HHà,HHà ,HHà,HHà -àT-àT,HHà2àà5àÌàFøøPAGEHEADING VERSOHEADFøøPAGEHEADING RECTOHEADEøøPAGEHEADINGFOOTINGVEøøPAGEHEADINGFOOTINGR, ?1(DEFAULTFONT 1 (GACHA 10) (GACHA 8) (TERMINAL 8)) CLASSIC TITAN CLASSIC TITAN HELVETICACLASSICMODERN HELVETICACLASSIC HELVETICA MODERN TIMESROMAN HRULE.GETFNMODERN " HRULE.GETFNCLASSIC # HRULE.GETFNCLASSIC HRULE.GETFNCLASSIC IM.CHAP.GETFN HELVETICA HRULE.GETFNMODERN!
