If you mean that REXX doesn't distinguish between a null string and an omitted string, that's true. My programs all use the null string in an argument to indicate omission, since that what you get with the ", ," idiom. So my program can decide it wants the "default" behavior at runtime without having to have two different CALLs or function invocations. I like it that way. :-) Alan Altmark Senior Managing z/VM and Linux Consultant Lab Services System z Delivery Practice IBM Systems & Technology Group ibm.com/systems/services/labservices office: 607.429.3323 mobile; 607.321.7556 alan_altm...@us.ibm.com IBM Endicott
