If possible, you should recode SPL subroutines as HP C/XL #define macro
directives, which permit parameters, and result in inline substitution.
Where appropriate (i.e., in functions), limit the scope of a #define
directive with a subsequent #undef directive.
Otherwise, you must recode the SPL subroutine as an HP C/XL independent
function. This can be awkward because variables that were formerly local
to the procedure and known to the subroutine have to be made available to
the new function. You can make variables available to new functions
either by declaring them as global (to all functions) or by passing them
as parameters.
