Hi,

I have a SORT step which uses same file for both SORTIN and SORTOUT like below -

//sortstep exec pgm=sort
//sysout dd sysout=*
//sortin dd dsn=xyz.a123,disp=shr
//sortout dd dsn=xyz.a123,disp=shr
//sysin dd *
omit cond=CONDITION
sort fields=copy
/*

Assuming the OMIT COND removed/omitted 'n' records, Does the file (xyz.a123 above) occupies the same space after execution of SORTSTEP as before or need LESS space.


Regards,
Murali Mohan K

Why dont you try it to see for yourself?

I think it will need/use less space.
