Blank Line Generation
If occasional blank lines are desired in a listing (usually to set off sections of code, or com-
ments), they may be generated by including -
' : ::;r:::' c :
{number}
at the desired spot in the source statements. {number} designates the number of blank lines
desired. {number} can be any absolute expression, provided the expression evaluates to a
positive integer (see "Symbolic Operations" below).
Non-Listable Pseudo-Instructions
The following pseudo-instructions do not appear in a listing -
!. .••••.•••
..i i
::::;F' C :::
Conditional Assembly
For reasons of complexity or length, it is occasionally desirable to selectively assemble only
parts of a module. This is particularly true during the debugging stage of longer, complex
assembly programs. "Conditional assembly" is the ability to designate certain portions of a
module for assembly, depending upon conditions established by the IASSEMBLE statement.
You may recall from the description of the IASSEMBLE statement earlier, there are options
called "conditions" available with the statement. These conditions -
