Assembly Listing
The choice of line number 16 is arbitrary here. At the end of the
assembly listing, a symbol table is printed showing the name and value
of each symbol in the file. A type field for each symbol, indicating either
absolute or relocatable, is included.
Certain types of source lines generate multiple instructions. Macro calls
often expand to several instructions. The .ENTER and .LEAVE
pseudo-operations can each generate more than one instruction. The
predefined subspace directives, such as .CODE and .DATA, result in a
space and a subspace declaration.
You have the choice of listing a section of assembled code in either the
compressed or expanded form. The placement of the .LISTON and
.LISTOFF directives determines which code will be expanded during
listing. The directive .LISTON tells the Assembler to expand the listing
of all subsequent source lines until a .LISTOFF directive is encountered.
.LISTOFF stays in effect until the occurrence of a .LISTON directive.
The default is .LISTON.
The directives .LISTON and .LISTOFF may be placed anywhere in the
source text and always go into effect immediately. The .LISTON and
.LISTOFF directives can be used as often as desired.
