SuperC - Do Not Report Spacing Changes Unless Within Quotes

There is an existing option, DLREFM (suppress reformatted lines from the listing) which although it does suppress the reformatted lines from the OLD file, it does not suppress them from the NEW file. Another option, REFMOVR, suppresses reformatted lines in both files.

We would like a new option (DLSPC?) that will suppress reformatted lines from both the old and the new file unless the reformatting is within quotes.

Ex 1 - I don't care that irrelevant spaces were removed:
OLD: CALL MYSUB (1,'TEST')
NEW: CALL MYSUB(1,'TEST')

Ex 2 - I don't care that the columns shifted or spaces were removed:
OLD: CALL MYSUB (1,'TEST')
NEW: CALL MYSUB(1,'TEST')

Ex 3 - I do care that relevant spaces were inserted:
OLD: CALL MYSUB(1,'TEST')
NEW: CALL MYSUB(1,' TEST')

Ex 4 - I do care that relevant spaces were removed:
OLD: CALL MYSUB(1,' TEST')
NEW: CALL MYSUB(1,'TEST')

    This was an interesting idea, and potentially useful, but far more complex to provide as a general purpose option than it might have appeared at first glance. For example, in the first quoted example, a space was completely removed before a parenthesis, which presumably had no effect in this case, but if a space had been completely removed changing "CALL MYSUB" to "CALLMYSUB" that would have had a significant effect. It would also be necessary to have options specifying the quoting convention (for example whether single or double quotes, and whether embedded quotes of the same type are doubled or escaped with backslash as in C) or equivalently one of a list of specific languages to assume for that purpose. It might also be necessary to ignore quotes appearing in language-dependent comment strings.

    What seems to be required here is not even a general comparison program like SuperC, but rather a special-case language-sensitive program to verify that the meaning of a program has been unchanged by reformatting. For compiled code, one solution to this is to compile the original code and reformatted code using the same compiler and options, then compare the binary object code output with the original (ignoring date stamps and similar).

    We are therefore declining this request, as we do not consider it a worthwhile use of our resources, given the complexity, the language-specific nature of the function and the specialised use case.

    Any status update from IBM? This RFE is still in submitted status. It was submitted a year and a half ago.

    Thank you.
