The built-in functions index(string, pattern [,start] ) and pos(pattern, string [,start] ) in my ARexx (Amiga Rexx, by William S. Hawes) manual seem to work completely the same. Index() is not mentioned among the extentions to the language standard. In his book "The Rexx Language", (second ed., 1990) Cowlishaw does not mention index() at all... Could somebody give the rest of the story?? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . S V A N T E K L E I S T . . . .

These functions do exactly the same thing, but the syntax is different. The reason for the inclusion of INDEX() is that it is what PL/I programmers are used to, and IBM wanted to make life easier for them. Eric
