evaltext as function?

[John Smith]

Is there a way to evaluate a text string as a function?

I know of EVALTEXT(shapename!thetext).

I want to use a function like EVALTEXT(
IF(user.row_1=1,"SETF(xxxxx)","SETF(yyyy)"))

The only way I can think of - UNTESTED - is to create dummy shapes with text
hidden and placing the "SETF(xxxx)" in the dummy.thetext then using the
function

IF(user.row_1=1,EVALTEXT(dummy1.thetext),EVALTEXT(dummy2.thetext))

Any recommendations.
