HP FORTRAN 77/XL Compiler by Erryl Johnson--Information Technology Group HP FORTRAN 77/XL is the Native Mode implementation of HP STANDARD FORTRAN 77 on the MPE XL operating system. HP STANDARD FORTRAN 77 is the Hewlett-Packard implementation of FORTRAN 77 that contains ANSI FORTRAN 77, MIL-STD-1753 extensions and some additional HP extensions. HP FORTRAN 77/XL is compatible with the HP FORTRAN 77/V compiler, which is supplied when HP FORTRAN 77/XL is purchased. HP FORTRAN 77/XL includes all the features of version A.00.09 of HP FORTRAN 77/V, plus some additional features and compiler directives. HP FORTRAN 77/XL VERSES HP FORTRAN 77/V The differences between HP FORTRAN 77/XL and HP FORTRAN 77/V are due to the architectural differences between MPE XL and MPE V, such as data alignment and floating point format. A compiler directive, HP3000_16, is provided to allow the architectural differences to be ignored if the user chooses not to modify existing user source code. An additional feature of FORTRAN 77/XL is code optimization, which allows programs to use machine resources more efficiently by using less space and running faster. HP FORTRAN 77/XL COMPILER DIRECTIVES The HP FORTRAN 77/XL compiler includes the following compiler directives, in addition to the ones implemented in the HP FORTRAN 77/V compiler. CHECK_OVERFLOW LITERAL_ALIAS OPTIMIZE SYSINTR CONTINUATIONS LOCALITY SAVE_LOCALS UPPERCASE HP3000_16 LOWERCASE SYMDEBUG VERSION The following HP FORTRAN 77/V compiler directives are not implemented in the HP FORTRAN 77/XL compiler.

The HP FORTRAN 66/V to HP FORTRAN 77/V Migration Aid is distributed with both the HP FORTRAN 77/XL and HP FORTRAN 77/V compilers, and the file name of the Migration Aid is identical for both compilers. This will not present any problems because the Migration aid is the same version for both compilers.
