Purely as a guess: The regular expression "mode" (BRE, ERE) might be set using an options string at the beginning of the regular expression. For example, according to https://www.regular-expressions.info/modifiers.html if you were processing regular expressions in Tcl, you would use (?b) at the beginning of the expression to force BRE mode, and (?e) to force ERE mode. It is possible that this or something similar would work in DFSORT's engine. It's fairly common, in my experience with different regex engines, for some set of the options shown on that page to be supported. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
