Problem Title:
Exemplar Galileo 3.2.5: Known issues with Galileo-generated XNF files


Problem Description:
Keywords: Galileo, Exemplar, XNFPREP, ERROR 3516, TIMESPEC

Urgency: Standard

1. XNFPREP gives ERROR 3516: File contains a mixture of symbols from the
   Unified and pre-Unified libraries.

2. Attaching a TS attribute to signals in Galileo like Example 7 on page
   D-28 of the Galileo Reference Manual may also cause problems.


Solution 1:

1. Error 3516 occurs because the TIMESPEC symbol in XNF file generated by
   Galileo is missing the Unified library attribute, LIBVER=2.0.0.  To
   remedy this problem, append this attribute to the TIMESPEC symbol record
   in the XNF file, for example:

   Old: SYM, $1I2, TIMESPEC, TS01=FROM:FFS:TO:FFS=40
	END

   New: SYM, $1I2, TIMESPEC, TS01=FROM:FFS:TO:FFS=40, LIBVER=2.0.0
	END

2. This is caused because the TNM attribute is incorrectly applied by
   Galileo with a prepended equals sign.  You must remove the equals sign
   in front of each TNMs in the XNF file to workaround this problem, for
   example:

   Old: EXT, INPUT, I,, =TNM=IN

   New: EXT, INPUT, I,, TNM=IN
