But ONLY if the utility is coded to use fopen() and not open(); fopen() supports the DD:ddname syntax, open() does not.
By practical experimentation, I found that z/OS Unix awk uses fopen(). I'll bet the cat utility does too but that cp uses open().

The DD:ddname format for a "legacy" dataset is a supported and documented feature of the C runtime library (even if not specifically for cat).

Would you distribute to customers code dependent on an unsupported feature?
