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

<lclx> 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.

Set the value of the variable with a SETA, SETL, or SETS directive.

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
$label  ; code
        INFO    0, "err":CC::STR:$a     ; Use string
