To manually run through Assembler you can do the following.

Go to the Net Express command prompt and run the following:

run mm370asm "C:\\Documents and Settings\\user\\My Documents\\testmap.bms" nodfhgen bal noasm sysparm(DSECT)

Where "C:\\Documents and Settings\\user\\My Documents\\testmap.bms"
is the path where your testmap.bms exists.

This will generate a testmap.bal which you can then rename to a .bms and use.

Additionally, LANG=COBOL2 is not correct.

This is based on the following:

http://publib.boulder.ibm.com/infocenter/txformp/v6r0m0/index.jsp?topic=/com.ibm.cics.te.doc/erziai00162.htm

So change to LANG=COBOL and then this was successful.
