My main argument is that if a particular source format is part of a programming language's identity (e.g., the columnar format of RPG, the "Statements start at Column 7, continuation is indicated in Column 6, C for comment in Column 1, labels in 1-5" format of FORTRAN, the "all lines are numbered, numbers serving both as sequencing and as labels" format of BASIC, &c.), the format can certainly EVOLVE to a certain extent (e.g., OPM RPG to ILE RPG) without fundamentally violating the language's identity, but if that format is discarded entirely (e.g., RPG to /free, BASIC to QBASIC, FORTRAN to Control Data's FTNTS format), then *it ceases to be the same language* and should be called something different (e.g., I've used, and most definitely LIKE, the QBASICs, but I flatly refuse to call any of them "BASIC").

My other argument is that if you aren't using a language's core features (e.g., The Cycle, and/or extremely close integration with native record-level access, for RPG), then you might not be using the best language for the task at hand.
