If the decision had been made for a case-insensitive file system (in fact, no such decision was ever made, neither for nor against, thus creating the problems), the implementation should not have been in JCL, which would require parallel implementation in numerous applications and utilities, but in Data Management itself, so that a mixed case argment in any of JCL, TSO, IDCAMS, IEHPROGM, SVC 99 text units, etc. would have equivalent results with no need for case conversion in the individual utilities.
