UDC / script comparisons (cont)
• differences:
• scripts can be variable record width files
• UDCs require lock access, scripts don’t
• script names can be in POSIX syntax, UDC filenames must be in MPE
syntax
• UDC name cannot exceed 16 chars, script name length follows rules for
MPE and POSIX named files
• EOF for a script is the real eof, end of a UDC command is one or more
asterisks, starting in column one
