In Classic and Object REXX, the expression N+1 would be evaluated and
passed to the
environment. To sustain this paradigm in NetRexx, it would have be a
java.lang method or some other java package method, or the invoking
environment (such as an editor).
My strong personal feeling is that having N+1 mean 'add 1 to N' in
NetRexx is a radical departure from Rexx convention.
I would much prefer an explicit "use in expression and replace with
result" operator such that N <<< +1 means 'add 1 to N'
Other candidates for N "use and replace" op expression meaning: N = N
op expression
N >< +1 Hard to type
N`+1 Hard to see
N~+1 Object Rexx
{N}+1 Extra characters
N^+1
N!+1 Conflicts with factorial
N@+1
"Use in expression and replace with result" could also be a prefix
operator such as:
`N+1 Still hard to see
^N+1
{N+1 If you use just one, how do you remember which one?
@N+1
I prefer the prefix form because of readability. The deciding factor
between ^ and @, my two favorites may be keyboard availability. Since
@ is used in other language constructs, I believe it is more generally
available.
Also this operator could be implemented in Classic and NetRexx, which
would help in maintaining Rexx consistency.
