You want to make sure you are not creating and destroying a LE environment for every call, or it will get expensive.
If your calling Assembler program is Language Environment-conforming, have a look in "z/OS V1R12.0 Language Environment Writing ILC Applications", section "14.5 Assembler Main Calling HLL Subroutines for Better Performance" http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/CEEA4180/14.5?SHELF=cee2bkc0&DT=20100628162151 If your calling Assembler program is not LE-conforming, go to "z/OS V1R13.0 Language Environment Programming Guide", "5.3 Chapter 30. Using preinitialization services" to read about the use of CEEPIPI http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/CEEA21C0/5.3?SHELF=cee2bkc0&DT=20110618162445 -- Regards, Gord Tomlin Action Software International (a division of Mazda Computer Corporation) Tel: (905) 470-7113, Fax: (905) 470-6507 On 2011-10-14 09:33, McKown, John wrote:
I know that I've seen somebody do this before. But I cannot remember how they did it. Does anybody have a code snippet that shows how to call a C subroutine like sprintf() or strncmp() from HLASM? Also the compile& link JCL would be appreciated. I've tried reading the LE manuals and the C manuals, but I'm just not finding it. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
