Hi everyone,
i am new to mainframes. i wanted to know how to create an IAM file.
i know that there is a TSO command called $IAM. i used that command to create an IAM. when i try to edit it,i get an error saying that "file allocated but not created. dd statement missing".

i also want to know whether one can create IAM file using File-Aid. if yes, how?

thanking you
swaroop

You need to include the "owner".

IDCAMS DEFINE:

DEFINE CLUSTER (NAME(HILQ.XXXX.FILEA) -
SHR (2 3) -
OWNER($IAM) -
FSPC(20 15) -
KEYS(013 004) -
CYL(1000 1000) -
VOLUMES(AAAAAA BBBBBB CCCCCC) -
RECSZ(0457 4089) -
NOREPLICATE -
REUSE -
SPEED -
NOIMBED -
INDEXED ) -
DATA (NAME(HILO.XXXX.FILEA.DATA) -
CISZ(4096) ) -
INDEX (NAME(HILO.XXXX.FILEA.INDEX) -
CISZ(2048) )
