Calculate Non-vsam space
Posted: Fri May 13, 2011 7:07 pm
Hello,
I'm working on a program which calculate the number of tracks occupied by non-vsam files (to begin i assume that none of the file is extended
or multi-volume).
My input is a list of file + the volser of each file.
I use both of it to read the Format-1 DSCB, but how to calculate the total of tracks occupied by the non-vsam ?
The FMT-1 gives me the TTR (DS1LSTAR field) but the result is not as precise as the one i get by performing a DSList or browsing
ISMF.
I know i could use either a DCOLLECT or an IEHLIST to get the info but I'm trying to do it using VTOC.
