I guess we can edit DASD records but not tape records.But i am not pretty sure.

And we can`t alter limit in GDG.

Hi,

We cannot edit tape files but we can override existing files. If you want to learn more about tape file handling just go through the material avialable in
http://publib.boulder.ibm.com/infocenter/iseries/v5r3/ic2924/info/rzatb/rzatb.pdf

We can change GDG limit by using ALTER GDG option of IDCAMS utility.

//JOBCARD...
//*-------------------------------------------------------------------*
//* Alter GDG limit
//*-------------------------------------------------------------------//*
//STEP1 EXEC PGM=IDCAMS
//SYSIN DD *
ALTER -
GDG -
LIMIT(20)
/*

20 is a new limit.

Bye,
Reddy.
