to_date

[BOB SHIFLETT <shifletb@SHENTEL.NET>]

I'm having a problem using the oracle to_date function in SQR V3.0.12.1

I get the error message :
 (SQR 4008) Unknown function or variable in expression: to_date
         to_date($end_date,'yymmdd') < to_date($begin_date,'yymmdd')

I have successfully used this function on one of our other unix boxes
running V2.4.2
If you should happen to know of a problem with this release of SQR or spot
errors
in code below (I have tried many different variations) please let me know.

thanks,

Bob
