Re: Evaluate an string.

Eval a 4gl statement within a 4gl module? No can do, *but* I can tell you how to dynamically execute perl code within a 4gl application. Yeah, Yeah, you wanted 4gl, but perl should be good enough to parse an expression, if this is all you want. It is also a fairly simple and almost portable way to add to 4gl tons of features like regexps, file or sockets (btw, find sockets for 4gl in my humble site) user group and password functions and indeed the whole bunch of goodies described in perlfunc. Sounds interesting? Have a look at the perlembed man page...
