z390_v1702.zip is now available for downloading from www.z390.info and the next monthly ZoomToSHARE session is on Wed. 2020-11-04 from 11-12 EST www.zoomtoshare.org.
See the z390_v1702_readme.txt file in the zip file for details about fixes and enhancements. There are new structured macro enhancements and perl enhancements for Linux users.
There is a updated test program zopcheck.mlc which tests all 2336 opcode and operand combinations supported by z390. This program has been assembled on both z390 and HLASM on mainframe to identify differences.
