Doesn't the real MVS LOAD only handle modules that have been processed by the link editor?

It will load a text deck into memory and return the address & length in R0 & R1. Make sure the your table is assembled with RMODE ANY so that it can be placed above the 16MB line. The DELETE macro will unload the TEXT deck. If you want to do this with native CMS services, issue the NUCXLOAD command to load the text deck and use the NUCEXT QUERY macro to return address & length information (extracted from the SCBLOCK). Starting the program name with an asterisk (e.g. "NUCXLOAD *TABLE MYTEXT") will make sure you don't accidentally try to "run" the program. Use "NUCXDROP DROP *TABLE" to unload the table. While this isn't particularly hard, I kind of like the MVS LOAD macro better.
