Close. For EXEC, you could use:
Symbol Operation
= or EQ equals
¬= or NE not equal
< or LT less than
<= or LE less than or equal to (not greater than)
> or GT greater than
>= or GE greater than or equal to (not less than)
For EXEC2, you could use:
-.-=--.-
|-EQ-|
|-¬=-|
|-NE-|
|-<--|
|-LT-|
|-<=-|
|-¬>-|
|-LE-|
|-NG-|
|->--|
|-GT-|
|->=-|
|-¬<-|
|-GE-|
'-NL-'
These can be found by doing HELP EXEC MENU and HELP EXEC2 MENU and then
looking under &IF.

Trying to think back, but didn't EXEC or EXEC(2) take the english word i.e.
&IF &A EQUAL &B ....
or am I getting old and confusing it with COBOL?

Since Rexx accepts either the not sign or \ as an alternate not sign,
and since the \ was foisted off on us a long time ago because of errors
in sending files with the "real" not sign, I have become accustomed to
seeing "\" and thinking "not". It is no different than accepting "^" as
a not sign, and similar to accepting "don't" or "dont" as meaning "do
not". I am surprised you haven't seen the conversation before.
I am not trying to force other people to conform to what seems natural
to me. I merely pointed out that each has his/her own idea of what is
natural. What seems natural to you may not seem so to others. I had been
programming 22 years before I ran across "\" as an alternate not sign
and did not see the "<>" notation for several years after that. Is it
any wonder that I do not see that "ugly" expression as natural? :-)

Richard Schuh
