There are actually very few, if any, truly reserved words in I4GL.
For example:

FUNCTION main(let)

	DEFINE let DECIMAL(3), decimal CHAR(9), date INTEGER, integer DATE

	LET let = 3
	LET decimal = "9"
	LET date = 2
	LET integer = mdy(3,2,1998)

END FUNCTION


This code compiles quite happily under both the c-code and the p-code
compiler, even producing an executable (which fails with a core dump when
run).  The C compiler has a fit if the code misuses C keywords (eg int,
for, sizeof), so you can argue that they are reserved in the c-code
version.

However, ignoring that, then here is a list of keywords which can be used
somewhere in I4GL with special significance.  It has been updated to
include almost all the keywords I can find in the Informix Guide to SQL
Version 7.2, so it also contains keywords which I4GL does not handle...
