MVS data set names are also case sensitive, but most user interfaces conceal this by translating to upper case. But the most direct interfaces show the case-sensitivity. In JCL you can create and access mixed-case data set names (use apostrophes). And in Assembler you can create and access mixed-case data set names (SVC 99; DCB) and mixed-case member names (STOW; BLDL; FIND). I think it's a disservice either of the HL interfaces to prohibit access to part of the namespace or of DfSMS to alllow manipulation of "invalid" names. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
