/* NAME: lookupfixdata
*
* DESCRIPTION: This function reads apar numbers from the 
*              standard input and writes fixdata stanza to
*              the standard output. It gets the fixdata stanza
*              from the fixdata database file which is in
*              top/HISTORY/fixdataDB file.
*
* PRECONDITIONS:  stdin.. newline separated list of apars
*                 fixdataDB file should exist
*
* POST CONDITIONS: None
*
* INPUT PARAMETERS: argv[1] contains the name of the fixdata database
*
* DATA STRUCTURES: None
*
* RETURNS: Fixdata stanzas for the apars on stdin.
