LOCAL
Basic form
LOCAL f.
Effect
Can only be used after the
FORM statement.
Saves the current value of the field f when you enter the routine and
restores it when you leave the routine.
You can also use LOCAL for field symbols and formal parameters.
With field symbols, it not only saves and restores the field reference
created using ASSIGN , but also the
contents of the field referenced when you enter the routine.
With formal parameters, please note that although changing the value of
the formal parameter does not affect the actual parameter after you
leave the routine (if you specified the formal parameter after
LOCAL ), the values of the formal and actual parameter within the
routine are always identical.
This contrasts with the VALUE specification (see
FORM ) where changing the passed field
within the routine does not affect the value of the formal parameter.
