ALLOC_ISET

Use the ALLOC_ISET command to allocate an IMOD file. ALLOC_ISET automatically invokes the INITIALIZE command after successful allocation.

Syntax

Use this format for the ALLOC_ISET command:

ALLOC_ISET [DDNAME ddname] NAME clname [VOLSER volser] {CYL|TRK} prim sec

Parameters

The ALLOC_ISET command takes these parameters.

ddname: DDname to assign. Be sure the name you specify does not duplicate a ddname in the JCL. Needed only if you wish to perform additional operations on the newly allocated ISET.
clname: Cluster name, from 1 to 38 characters.
volser: Volume serial number of the volume to contain the data set.
CYL: Space allocation (prim and sec) is specified in cylinders.
TRK: Space allocation (prim and sec) is specified in tracks.
prim sec: Space, in cylinders or tracks, for primary and secondary extents.

Usage Note

After you allocate a file, you can perform operations on the new file by using the ddname that you assigned.
