This should be the easiest thing in the world. I'm trying to use dialog manager to set tomorrow's date:
-SET &MEASDATE = &DATE;
-SET &NEXTDATE = DATEADD(&MEASDATE,'D',1);

Result:
INVALID TYPE OF ARGUMENT #1 FOR USER FUNCTION DATEADD

Anyone?
(I HATE WF date handling)


Thanks.

Unfortunately, you have to convert the "alpha" Dialogue Manager date to a date field before using DATEADD.

E.G.:
-*-- Determine Period End Date 24 months prior to selected Period ---
-SET &DT24 =
- DATECVT( DATEADD(DATECVT(&F1V1,'I8YYMD','YYMD'),'M', -24),'YYMD','I8YYMD');


The inner DATECVT converts the DM variable to a date field, then DATEADD is applied, then the outer DATECVT converts the DATEADD result back to an alpha DM variable.

Your code:
-SET &MEASDATE = &YYMD;
-SET &NEXTDT1 = 
- DATECVT( DATEADD(DATECVT(&MEASDATE,'I8YYMD','YYMD'),'D', 1),'YYMD','I8YYMD');

-SET &NEXTDT2 = CHGDAT('YYMD','MDY',&NEXTDT1,'A8'); 

-SET &NEXTDATE = EDIT(&NEXTDT2,'99/99/99');                           

-TYPE &MEASDATE - &NEXTDATE

I ALWAYS use YYMD formatted dates in calculations. You can always change the format for printing purposes

ok, that's helpful. to add one more question though:

my initial date (&MEASDATE) is sometimes passed into the fex as mm/dd/yy string. How would I accomplish the same thing if I start with "9/24/07" for example?


Thanks.

Sorry 'bout that.

-SET &MEASDATE = &DATE;

-*-- Strip the slash separator character
-SET &MEASDT1 = EDIT(&MEASDATE,'99$99$99');

-*-- Convert the variable to a Date, add a day, convert back to integer
-SET &NEXTDT1 = 
- DATECVT( DATEADD(DATECVT(&MEASDT1,'I6MDY','YYMD'),'D', 1),'YYMD','I8YYMD');

-*-- convert from yymd to mdyy
-SET &NEXTDT2 = CHGDAT('YYMD','MDY',&NEXTDT1,'A8'); 

-*-- add date separator character
-SET &NEXTDATE = EDIT(&NEXTDT2,'99/99/99');                           

-TYPE &MEASDATE - &NEXTDATE

for DM dates, i use the AYMD and the AYM functions
-SET &TODAY = &YYMD ;
-SET &TOMORROW = AYMD( &TODAY, 1, 'I8YYMD');

We on the Point love FOCUS date functions, wttw.
there's an entire book on the subject, which you can order from the Tech Support site.

-SET &DT1 = &YYMD ;
-SET &DT2 = AYMD(&YYMD ,1, 'I8' );
-TYPE TODAY: &YYMD TOMORROW: &DT2
-EXIT


note: you may need need to set DATEFNS
to put slashes or dashes you will need to add a few statements
