DATE and UNITS problem

I have a 4gl program that uses the DATE and UNITS as in main define d1 date define d2 date let d1 = "1/31/1995" let d2 = d1 + 1 units month display d2 end main The program fails because it trys to assign d2 a value of "2/31/1995" which is of course an invalid date and results in the following error: FORMS statement error number -1267. The result of a datetime computation is out of range. I am using ONLINE 5.01.UD2 and 4GL RDS 4.11.UC2. I have also got similar results on ONLINE 5.03.UC1 and 4GL RDS 4.12.UE1. Has anyone encountered this? Is this a known "bug" and what is the workaround? Thanks. -------------------------------------------------------------------------------- Alvin Koh Internet: Alvin_Koh@email.mot.com Senior Systems Engineer, MIS alvinkoh@pts7.pts.mot.com Motorola Electronics Pte Ltd - AMK Phone: +65 486-2055 Paging Products Group Fax: +65 481-2840 Asia/Pacific Paging Subscriber Division --------------------------------------------------------------------------------
