Trying to learn the Z390 Interactive debugger…based on an email I got from Abe from the google user group, who suggested “EXEC.BAT path/file noloadhigh test”. So from there I got to a starting place of “exec MyStuff/case noloadhigh test noinit”. From there I typed h…for help. From there I believe the PSW or PSW16 command and the offsets in the program.PRN maybe everything I need.
