Steven,
As others have said sometimes you need to include OSMACRO and use OS Macros. The supported macros are listed in the CMS User Guide. Rather than SNAP , you might want to use the PER.
The CMS in the six-packs has the PER command included (Program Event Recording) which is extremely powerful and very useful for de-bugging programs.
For seeing what is going on the LINEDIT macro is pretty useful. Its documented in the CMS Command Reference manual.

Subject: [h390-vm] SNAP Macro
I have been reading Sharon Tuggle's book "Assembler Language
Programming: Systems/360 and 370" and it makes use of a macro SNAP on
OS (MVS etc) which, from what I can tell, produces some kind of dump
output of the program state.
This does not seem to be defined while assembling on CMS. Is there an
equivalent? Or do I need to do something to include a specific macro library?
