C Revision 1.2  1999/06/21 22:43:40  gdsjaar
C Fixed more uninitialized variables; one was causing core dump on g77
C compiled executable.
C
C VERSN was not consistently defined -- now 10 characters everywhere
C
C Updated so full version string output
C
C Added capability to debug memory using unit specified in EXT99
C variable. Similar to STRTUP in SUPLIB
C
C Cleaned up some other code
C
C Upped version
