That's not the best of both worlds, because the next person to read the 
code will still see you calling 'closef()' or 'openf()' or something like 
that instead of the actual API name.

A better solution is simply to put a "callp" in front of the API name. 
It's not a big inconvienience!

Every language has reserved words.  Try to name a variable "for" in C. Or 
"sizeof".  Try to name a variable "dim" or "let" in BASIC.  Every language 
has reserved words.

RPG is nice enough to provide a way around the problem by letting you add 
a "callp" to the start of the line, something that no other language does 
(to my knowledge.)  Furthermore, none of the API names are a problem when 
used in an equasion.  For example, the following works fine:

    x = close(fd);

RPG is smart enough to know that close isn't an op-code in this case 
because it's after an equal sign.  I think they did a great job with the 
RPG compiler.
