Syntax of numeric local labels

7.11 Syntax of numeric local labels

When referring to numeric local labels you can specify how armasm searches for the label.

Syntax

n[routname] ; a numeric local label
%[F|B][A|T]n[routname] ; a reference to a numeric local label
where:
n
is the number of the numeric local label in the range 0-99.
routname
is the name of the current scope.
%
introduces the reference.
F
instructs armasm to search forwards only.
B
instructs armasm to search backwards only.
A
instructs armasm to search all macro levels.
T
instructs armasm to look at this macro level only.

Usage

If neither F nor B is specified, armasm searches backwards first, then forwards.
If neither A nor T is specified, armasm searches all macros from the current level to the top level, but does not search lower level macros.
If routname is specified in either a label or a reference to a label, armasm checks it against the name of the nearest preceding ROUT directive. If it does not match, armasm generates an error message and the assembly fails.
