Uppercase Letters (FORTRAN 77 only)

If your program has uppercase letters in any identifiers, dbx recognizes them. You need not provide case-sensitive or case-insensitive commands, as in some earlier versions. (The current release of f90 is case-insensitive.)

FORTRAN 77 and dbx must be in the same case-sensitive or case-insensitive mode:

• To compile and debug in case-insensitive mode, do so without the -U option. The default then is dbxenv case insensitive.

  If the source has a variable named LAST, then in dbx, both the print LAST or print last commands work. Both f77 and dbx consider LAST and last to be the same, as requested.

• To compile and debug in case-sensitive mode, use --U. The default is then dbxenv case sensitive.

  If the source has a variable named LAST and one named last, then in dbx, print LAST works, but print last does not work. Both f77 and dbx distinguish between LAST and last, as requested.

  Note -

  File or directory names are always case-sensitive in dbx, even if you have set the dbxenv case insensitive environment attribute.
