No, throwing off all your safeguards would be using internally defined data structures or "i" specs to define file layouts. Nobody is suggesting going back to that. There have been several discussions recently about mapping sql "select" and "fetch" operations into MODS, DS arrays, internally and externally defined data structures, variables. All those ideas seem to be promoted with impunity.

What if you use sql select xyz into :var, then someone changes the data type for "xyz"? How much of a safety net do we need? With this RLA technique, I already discovered that if the length of the data structure in the "d" spec gets out of sync with the length in the "f" spec, the compiler will generate an error.

What really is so meaningful about a keylist vs. a data-structure key with sub-fields?
