PDP-11 Notes

MACRO-11 Assembly Language

This section contains notes taken from MACRO-11 manuals, primarily PDP-11 MACRO-11 Language Reference Manual (AA-V027A-TC).

DIGITAL’s standard source line format is shown below:

    Label – begins in column 1
    Operator – begins in column 9
    Operands – begin in column 17
    Comments – begin in column 33

Section 6.1 of that manual (page 52 of the PDF) talks about there being a “line printer format” and a “teletype format”. However the listing files that I produce all seem to be in the line printer format. I can’t find a command line switch or an assembler directive that will switch to teletype format.

Sections 9.2 and 9.3 show the RT-11 command format to invoke MACRO-11.
