I am fairly certain that E-Basic/VBA does not have anything like an eval() function.<br>

Oh, I see why that's not working now, the logic was overwriting the Attribute.<br>
<br>
Still, it would be good to know if you pass a string as an expression. I've search the documentation and some VB stuff online, but I haven't seen an eval() like function. Has anyone else used/seen something like that in E-Basic?<br>
<br>
Thanks,<br>

Dear Group,<br>
I'm trying to streamline some of my inline code in a Touch Screen task. Is it possible to pass string values as execuatable pieces of code in E-Basic? I can do this in MATLAB (I think) and R using and eval() function, but is there an analogue in E-Basic?<br>
<br>
I've tried the following 'for' loop to assign an object border width using the string returned from the HitTest function (Objects are named "R0" through "R7"). I can compile the script fine, but it won't actually change the attribute value for some reason. Perhaps I just need a second set of eyes to point something out. Any suggestions would be welcomed! Thanks, Jake<br>

Set MouseResp = CMouseResponseData(Question.<u></u>InputMasks.Responses(1))<br>
Hit = theState.HitTest(MouseResp.<u></u>CursorX, MouseResp.CursorY)<br>
Dim i as Integer<br>
Dim theBorder As String<br>
For i = 0 To 7<br>
theBorder = Hit & "BW"<br>
If i = CInt(Mid(Hit,2,1)) Then<br>
c.SetAttrib theBorder,"5"<br>
Else<br>
c.SetAttrib theBorder,"0"<br>
End If<br>
Next<br>
