here what does the dd1 and catlg statements imply exactly?

Hello,

dd1 - where to perform the specified operation
catlg - specifies what operation to perform

so what abt the vol=ser=tmp000
does it tell that the particular dataset should be stored in tmp000 volume of the unit 3350. if so do we have to provide the volume in both the statements.
thanx

Hello,

so what abt the vol=ser=tmp000

That is what IEHPROGM expects.

does it tell that the particular dataset should be stored in tmp000 volume of the unit 3350

It says to create a catalog entry pointing to tmp000 for the named dataset - it does not create the dataset.

if so do we have to provide the volume in both the statements.

If you try to use IEHPROGM, you must specify both.

IEHPROGM is not a good tool for normal use. Creating/cataloging datasets is better done with jcl or tso/ispf.
