Compiler Constants ================== `g77' strictly assigns types to _all_ constants not documented as "typeless" (typeless constants including `'1'Z', for example). Many other Fortran compilers attempt to assign types to typed constants based on their context. This results in hard-to-find bugs, nonportable code, and is not in the spirit (though it strictly follows the letter) of the 77 and 90 standards. `g77' might offer, in a future release, explicit constructs by which a wider variety of typeless constants may be specified, and/or user-requested warnings indicating places where `g77' might differ from how other compilers assign types to constants. Note: Context-Sensitive Constants, for more information on this issue.
