General rules for coding the ASMADOPT ASSEMBLE file

Code in columns 2 through 71.
Do not put a comma in front of the first option in your macro.
Begin any continuation lines in column 16 and place a non-blank character in column 72 of the previous line. You can break the coding after any comma.
Place an END statement after the macro instruction lines.
Include only those options or DDNAMES that you want to change. High Level Assembler uses the IBM-supplied defaults for the unchanged options and DDNAMES.
