Object Modules

The ASMDASM disassembler component of the HLASM Toolkit Feature can reconstruct object modules from (a) load modules, (b) program objects, (c) CMS modules, and (d) VSE phases. It is described in the HLASM Toolkit User's Guide, GC26-8710, Chapter 3. It has been available since December 1995, and ha

PDS vs. PDSE

PDSEs have been available for a long time, and provide many advantages over PDSs. Why are people reluctant to use PDSEs? John Ehrman -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua

Re: EXEC Above the Bar (Was Large Page Support)

CSECTs are restricted to 16MB only if you generate traditional OBJ object files, because its length and address fields are 3 bytes long. As Peter said, the total length in a single assembly will be less than 16M. *BUT* if you specify the NOTHREAD option you can have as many very larget CSECTs as y

You might consider the string-search capabilities of SUPERC, and use a REXX exec to set up the data set names. John Ehrman (-- Referenced Note Follows ) Sent: Thursday, April 10, 2008 3:38 AM We have a requirement to search for a textstring i a lot of datase

Re: HLASM Macro Call Question

There's no need to do your own parsing -- as Steve Smith (I think it was) suggested, check the AINSERT statement: it was designed for exactly this kind of situation. Also, the NOCOMPAT(SYSLIST) option sometimes helps for substituted operands that are a list (like (A,B,C)), but won't help for opera
