Input format for DOWK subroutine?

[sagobogger]

I can't get the DOWK subroutine to return a result. My input date is a YYMD and the code is:

MYDAY/A4=DOWK(MYDATE,MYDAY);

and it returns a blank for MYDAY. Do I need to convert my YYMD date to another format for this to work?

Never fails, just when you give up, you find the answer yourself

DOWK likes old style dates so this works:

MYDATE_2/I8YYMD=MYDATE;
MYDAY/A4=DOWK(MYDATE_2,MYDAY);
