Arithmatic Operands (AREV Specific)

Hello All,
Arithmatic Operations Substitution
Eg Val Operator Val
10 * 1010 / 1010 - 1010 + 10Operand=*'
Ans=Val1 Operand Val2
How do I use a variable as the operand instead of actully putting the operand in the equation.
I solved this using a Case statement but I wanted to know if there is a way to do this in one line of code where the Operand Variable just changes.
Thanks!!!

I don't think there is a way to do this. I'm curious what application would benefit from such a scheme.

One way is to write a symbolic (maybe in voc), use dictcompile, run calculatex, and then call the function name stored in a variable @functionname(x,y) etc…
I once wrote an interpreter program to do this on a screen so that you could write and resolve formulae on the fly.

Val1 Operand Val2
Would be alot easier than
Operand=*'
begin case
case Operand=*' ; Val1 * Val2case Operand=/' ; Val1 / Val2case Operand=+' ; Val1 + Val2case Operand=-' ; Val1 - Val2end case
And this could be used in any application where you want to allow arithmatic operations on Values by the users.
Point being I dont want to have to code the same line of code 4 times in a case statement when I could do it in 1 line if it is possible.

I understand what you're trying to do. I just am trying to get a feel for why? The only things I can think of off the top of my head that would benefit from such a thing would be calculator or spreadsheet programs.
Anyway, I think the operators must be evaluated at compile time, not run time, which is why the functionality you want doesn't exist.
