Gee, Didn't anyone take this seriously ??  I know Hans won't see it till
monday,
but I thought at least someone would be curious about how the parser would 
interpert these.  Maybe you thought I was kidding. 

These are all valid statements in RPGIV,   How in a free format environment 
without Keywords, and/or special characters will the parser perceive these?
(BTW, IBM did the special character idea for their stuff using the % for
BIF's,
 They could have been consistent perhaps sticking with the *)

Note;  the 

CF UPDATE CHAIN READ

Actually has two valid meanings in RPGIV(depending on which position
you put stuff)

I guess we may findout what the parser thinks of our file names, field
names,
and variable names when we go to compile the stuff eh?

As an anecidote,  I remember sitting with the developer of the source level
debugger while it was still in design mode.    He was talking about how good

the parser was,    I said,   "Key in   WHEN WHEN.....  "

He did and the debugger "Thru up" so to speak.  I said that's what will
happen
if I have a variable  named WHEN.  Everyone in the room thought it was very 
funny.

I been thru this phase before,  and I want to be sure that things work like
we 
think they will.  Remember we're affecting about a Million programmers here,
who all have their own ideas about file, field, and variable names.  

For example, on the CF UPDATE CHAIN READ statement
Just what should the compiler take for granted?  How will it really
know what I meant?   And, No I don't think quotes 'UPDATE'  (like SQL) will 
work.   You tell me why. 

This is the fun part.
