7.2.2
LCLA, LCLL, and LCLS
The
LCLA
directive declares a local arithmetic variable, and initializes its value to 0.
The
LCLL
directive declares a local logical variable, and initializes its value to
{FALSE}
.
The
LCLS
directive declares a local string variable, and initializes its value to a null
string,
""
.
Syntax
<

variable
where:
<
lclx

is one of
LCLA
,
LCLL
, or
LCLS
.
variable
is the name of the variable.
variable
must be unique within the macro that
contains it.
Usage
Using one of these directives for a variable that is already defined re-initializes the
variable to the same values given above.
The scope of the variable is limited to a particular instantiation of the macro that
contains it (see
MACRO and MEND
on page 7-27).
Set the value of the variable with a
SETA
,
SETL
, or
SETS
directive (see
SETA, SETL, and
SETS
on page 7-7).
See
GBLA, GBLL, and GBLS
on page 7-4 for information on declaring global variables.
Example
MACRO ; Declare a macro
$label message $a ; Macro prototype line
LCLS err ; Declare local string
; variable err.
err SETS "error no: " ; Set value of err
