Description of DPYPAK for 7.02
|
|
|
|
The new copy of DPYPAK differs from the old in three significant
|
|
ways.
|
|
|
|
o Character attributes for terminals with such display modes as
|
|
reverse video, blink etc. Use of these character attributes is
|
|
described internally in the source code.
|
|
|
|
o Improved output performance by using the new .TOISO (Image
|
|
OUTSTR) arguement to the TRMOP. UUO in 7.02. Use of this
|
|
TRMOP. also allows output without having to reset the CRLF and
|
|
PAGE settings of the terminal by DPYPAK. Caution must be used
|
|
however if FORTRAN I/O will be interspersed with DPYPAK I/O
|
|
since the FORTRAN I/O will still be interfered with by the
|
|
monitor.
|
|
|
|
o Support for FORTRAN version 7 chracter strings in output
|
|
section routines. Pre-version 7 integer strings are still
|
|
supported, and FORTRAN strings have been made available to
|
|
assembler language programs if they use the FORTRAN v7 calling
|
|
conventions.
|
|
|
|
|
|
Several terminal types have been commented out of the code and are
|
|
presently unsupported because it was not possible to test them with the
|
|
new enhancements. Support for Zenith/Heath 19 terminals has been added
|
|
however because they were available for testing. If anyone can test the
|
|
terminals that have been commented out, the developers would be
|
|
interested in knowing of it.
|
|
|
|
Further, any behaviour which is not upwards compatible from
|
|
previous versions should be considered bugs, with one exception: Any
|
|
routine which is called with extra arguements which previous versions
|
|
have ignored, will not work correctly since DPYPAK now uses the
|
|
arguement count to determine the wether a character attribute word is
|
|
sent to it, and will attempt to use the extra arguements for that
|
|
purpose.
