Uppercase Letters

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.

Fortran 95 and dbx must be in the same case-sensitive or case-insensitive mode:

• Compile and debug in case-insensitive mode without the -U option. The default value of the dbx input_case_sensitive environment variable is then false.

  If the source has a variable named LAST, then in dbx, both the print LAST or print last commands work. Fortran 95 and dbx consider LAST and last to be the same, as requested.

• Compile and debug in case-sensitive mode using -U. The default value of the dbx input_case_sensitive environment variable is then true.

  If the source has a variable named LAST and one named last, then in dbx, print last works, but print LAST does not work. Fortran 95 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 dbx input_case_sensitive environment variable to false.
