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

There is an OS version of DSF which is available as module ICKDSF.
Would it be possible to OSRUN that module?ADMIN@TRITU.BITNET (Turkeer TUNCARAL) (01/15/88)
>Imagine if your favourite program was only available as an IPLable >card deck??!! First of all, you don't forget all the favourite programs was developed from their card decks. DSF is available only in card deck because it supports a <stand-alone> and the following operating system versions: OS/VS1 OS/VS2 MVS MVS/XA DOS/VSE AF3 S/370 As you see, there is not CMS support but S/370 mode is ok. It may be a program -except DSF can do the same thing- in non-IBM products but there is no CMS version of DSF. You are right for your part. IPL'ing a card image copy of a program is a pain but would not a CMS copy module of DSF be much larger than its IPL'able copy. IPL'able card deck contains over 4400 records. I suggest you to send your comments to your IBM representative and branch office with your bad compliments(??!!).

The MVS/XA load module for ICKDSF is 338K. I don't know much about VM, but it seems to me that there's no problem running a 338K program under CMS. If you need it (and it sounds like some people do), I suggest that a SHARE requirement be submitted to IBM. Just write the business care carefully -- why do you need it, and how will it benefit IBM to do it. It shouldn't be too hard for IBM (they have the source!) to create a CMS version out of the standalone version of dsf. /Leonard
