RE: Error in the EVAL Statement?

[Jim Langston <jlangston@xxxxxxxxxxx>]

In every language I've seen -(variable name) "flips the sign".  RPG is no 
exception.

eval MyVar = -10
Eval MyOtherVar = -MyVar
is the same as saying MyOtherVar = -(-10) which is +10.

Jon,

you say that preceding a variable name with a sign is legal syntax - but
that begs the question:

what is produced by this syntax?  ie.  if you precede a variable with a neg
sign, will it flip the sign of the variable (pos to neg or visa versa) or
will it work like the opposite of %abs()? where it would always provide the
negative representation of the number, regardless of what it's original
sign is.

just curious...
