[SOLVED] Converting Alpha to Numeric?

When using the following code,
-DEFAULT &VAR_YEARMONTH = 200810;
-SET &CYEAR = SUBSTR(6, &VAR_YEARMONTH, 1, 4, 4, A4);
-SET &P1YEAR = EDIT(SUBSTR(6, &VAR_YEARMONTH, 1, 4, 4, A4)) -1;

I get the error

0 ERROR AT OR NEAR LINE 5 IN PROCEDURE mrheaderFOCEXEC *
(FOC281) ALPHA ARGUMENTS IN PLACE WHERE NUMERIC ARE CALLED FOR

The error only comes up when I try to do a "-1" on the third line.
I'm sure it's obvious, but I don't see it.

Here are a few tips:

&variables are not specifically numeric- they are always just a string. If the value is a valid number then it it can be used in a numeric operation without any conversion. So you could just pull out what you need with an edit and subtract 1.

-DEFAULT &YRMTH
-SET &CYEAR=EDIT(&YRMTH,'9999');
-SET &P1YEAR=&CYEAR.EVAL - 1;

Also, the guidelines say that &var names should not be more than 12 characters.

-SET &ECHO=ALL;
-DEFAULT &VAR_YEARMONTH = 200810;
-SET &CYEAR = SUBSTR(6, &VAR_YEARMONTH, 1, 4, 4, A4);
-TYPE &CYEAR
-SET &P1YEAR=&CYEAR-1;
-TYPE &P1YEAR
-*-SET &P1YEAR = EDIT(SUBSTR(6, &VAR_YEARMONTH, 1, 4, 4, A4)) -1;

You are mixing an alphanumeric subroutine with arithmetic. You don't need that last line. You can also use EDIT instead of SUBSTR to extract the year (fewer parms).

Oops, didn't post the correct code earlier.
