MACRO-10 STRUCTURED PROGRAMMING MACROS Page 1 ABSTRACT 11/21/78 MACRO-10 STRUCTURED PROGRAMMING MACROS ABSTRACT This is a set of macros in a MACRO-10 Universal file implementing the structures IF/ELSE/ENDIF, WHILE/ENDWHILE, REPEAT/UNTIL, CASE/WHEN/ENDCASE, and LOOP/EXITIF/ENDLOOP to be used for structured programming in MACRO-10. The macros allow nesting up to a depth of 510 levels, and accept conditionals using AND, OR, and NOT, which may be nested to any depth.
