7.11 Syntax of numeric local labels
When referring to numeric local labels you can specify how armasm searches for the label.
Syntax
nroutname ; a numeric local
label%[F|B][A|T]nroutname ; a reference to a numeric local
labelwhere:
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.Related concepts
