https://communities.sas.com/t5/SAS-IML-Software-and-Matrix/SAS-6-12-IML/m-p/29507#M139 I would advise upgrading to the most recent version available to your customer. Almost all changes to SAS/IML are designed to be source-level backward compatible with existing releases. That said, SAS itself has changed quite a bit since V6 of IML, and I can't guarantee that there won't be some inconsistencies. The output may look cosmetically different, because current SAS/IML uses the SAS ODS system, which V6 did not. Aside from that, the basic functionality that was as in V6 is still there, plus A WHOLE LOT MORE, including SAS/IML Studio.

Also, consider that SAS and its components have come a long way since SAS Version 6, so your enterprise/organization should really be more active with maintaining a more "current" and "vendor supported" production SAS environment, if considered mission-critical.<BR /> <BR /> Scott Barry<BR /> SBBWorks, Inc.<BR /> <BR /> Migration<BR /> Lead Your Organization to SAS®9<BR /> <A href="http://support.sas.com/rnd/migration/" target="_blank">http://support.sas.com/rnd/migration/</A><BR /> <BR /> What's New in<BR /> SAS® 9.0, 9.1, 9.1.2, and 9.1.3<BR /> <A href="http://support.sas.com/documentation/onlinedoc/91pdf/sasdoc_913/whatsnew_10110.pdf" target="_blank">http://support.sas.com/documentation/onlinedoc/91pdf/sasdoc_913/whatsnew_10110.pdf</A> Sun, 31 May 2009 13:35:25 GMT https://communities.sas.com/t5/SAS-IML-Software-and-Matrix/SAS-6-12-IML/m-p/29508#M140 sbb 2009-05-31T13:35:25Z
