Hi Muni,

Just a minor (and probably obvious) cautionary note: the POINTER facility discussed in Dimandja's excellent source bears no relationship to the POINTER clause used by some COBOL verbs, such as INSPECT and UN/STRING.

Also, most discussions of POINTER cite its use in processing linked lists, but most of the "forum" buzz about it relates to its use in accessing system control blocks.

Regards, Jack.

And to follow-up on that last post:

- USAGE POINTER and SET xxx TO ADDRESS OF
are extensions to the '85 ANSI/ISO Standard and are *not* particularly portable across implementations that have this extension

- POINTER in INSPECT and <UN>STRING are ANSI/ISO conforming and quite portable

- The 2002 ANSI/ISO Standard introduces &quot;based data items&quot;, USAGE POINTER and SET ADDRESS features
