proc argument

pab

Hi!
Please tell me why it works with num, but does not work with string?

it work:
PROC main
    test 1;
    test 2;
ENDPROC

PROC test (num x)
    IF x = 1 THEN
        ...
    ELSEIF x = 2 THEN
        ...
    ENDIF
ENDPROC

it will be error:

PROC main
    test first;
    test second;
EMDPROC

PROC test (string x)
    IF x = first THEN
        ...
    ELSEIF x = second THEN
        ...
    ENDIF
ENDPROC

Don't use "test" as proc identifier. It looks like it's reserved.

This syntax seems to work:

   PROC abc(string x)

        IF x="first" THEN

        ELSEIF x="second" THEN

        ENDIF

    ENDPROC

    PROC abcd(num x)

        IF x=2 THEN

        ELSEIF x=3 THEN

        ENDIF

    ENDPROC

Also your syntax when calling:
  Test "first";
To indicate that it is passing a string into the procedure.
And, same as Maxim's example, you need to have the quotation marks to indicate string data type:
IF x = "first" THEN
UNLESS it is the name of an already declared string data.

The quotation marks. Here's what I missed when working with string. Thanks!

p.s.

I used "test" just for the sample code
