Now I am on a computer with VFP.

That is right: eval() by itself doesn't work.

The following, however, works:

Sample program:

* Please evaluate the following expression in the watch window:
* Application.Eval("randomnumber()")

SET STEP ON
* Just a few sample commands:
x = 5
y = 10
x = 4
y = 2

function randomnumber()
return rand()

WARNING: This worked, but gave me a fatal error later. I found fatal errors common when trying to pull special tricks in the debugger (even some advanced functions that are documented).

Another alternative is to evaluate the following two expressions:

Application.DoCmd("MyResult = RandomNumber()")

* and:

MyResult

Again, RandomNumber() is a UDF, of course.
