OPENSEQ Universe vs Unidata

[DonQuixote]

In Universe, if the sequential file doesn't exist the ELSE statement can CREATE a sequential file.
But, what do you do in Unidata.  The Command CREATE does not exist.  I've tried the APPEND option in a WRITESEQ statement but the error is that the file is not open.  Any suggestions?

In Unidata you can do an ELSE NULL on the OPENSEQ, and then when you WRITESEQ variable APPEND ON buffer ... it'll create the file.  If you really want to create the file you can execute a "touch" on it via AIX, but then you have to know the path to the file and that can get to be a little problematic to read the VOC pointer and figure all that out.
