Before you can debug an Assembler program, you must compile it for debugging either in the IDE or from the command line. The compiler generates an Assembler .390 file.
run mm370asm filename ANIM [otherDirectives];where filename is the name of your Assembler module, and otherDirectives can be any additional Assembler compiler directive options as required. The resulting filename.390 file is placed in the current directory.
Note that, if you are compiling for debugging from the command line and later rebuild the application from within the IDE, the debugging information produced from compiling from the command line is deleted if the IDE is not configured to produce it as well.
