Control Listing of Substitution Symbols
.sslist
.ssnolist
Two directives enable you to control substitution symbol expansion in the list-
ing file:
-
The .sslist directive allows substitution symbol expansion in the listing file.
The expanded line appears below the actual source line.
-
The .ssnolist directive suppresses substitution symbol expansion in the
listing file.
By default, all substitution symbol expansion in the listing file is inhibited. Lines
with the pound (#) character denote expanded substitution symbols.
This example shows code that, by default, suppresses the listing of substitu-
tion symbol expansion, and it shows the .sslist directive assembled, instructing
the assembler to list substitution symbol code expansion.
