Re: CF - One last question

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

Every free format programming language I program in, C, Pascal,
Basic, and a lot of others, have a list of "reserved words".  A reserved
word is a word you can not use as a function, variable, value, etc...

It is a command, and they are reserved just to prevent this situation.

Like in Basic a list of reserved words might contain:
FOR NEXT READ PRINT WHEN DO WHILE etc...

In a free format programming language some things can be very
ambiguous and so there are rules.

The easiest way, and in keeping in step with all the other free format
programming languages, would be to have a set of reserved words
for RPG.

READ READE DOU UPDATE IFNE etc...

Which means that if one of those reserved words appears in a statement
it is a command, not a user defined variable, function, tag, etc...
