The reasons I don't like using the IPLable DSF for formatting VSAM
minidisks under CMS are as follows:
1) It takes a L-O-N-G time to PUNCH the DSF cards to your reader
and IPL them. We use the ICKDSF EXEC given in the DSF manual.
Once DSF has been IPLed, you have to wakeup the DSF program
with a console interrupt - but ONLY after it has finished
IPLing. DSF gives no indication that it is expecting an interrupt.
It just sits there.
2) Having to IPL the DSF program means that you destroy your current
CMS environment, which has to be re-created when you finish DSF.
These problems are compounded, since the user I have who uses VSAM
is very short of disk space. This means he has to DEFINE temporary
disks for VSAM, and re-format them each session. What would be nice
is a little program (like FORMAT) that runs under CMS, but which
formats VSAM disks!
Surely this is not too much to ask? This is, after all, the
20th Century!
Imagine if your favourite program was only available as an IPLable
card deck??!!
