Multiline VBScript Label Expressions in Arcpy

Question

I am able to set simple label expressions, but when I try to set multiline expressions (which all VBScript expressions are) it does not get copied into the expression box properly. I have tried using Python's triple quote technique for multilines but that only seperates each line with a tab in the expression window. Anyone know of a way to do this? If so, does the label class need to be set to 'advanced' first, or is it possible to automate this aspect as well?

Alternatively, loading in precreated expression files would work just as well if not better if this is possible to script.

This is with the use of the Maplex extension.

EDIT

Basically this code below needs to be pasted into the expression box with Arcpy. One line works just fine, but because there are multiple lines, I can't get it to paste it properly.

Function FindLabel ( [SUPP_NO], [SUPP_SUFF])
IF [SUPP_SUFF] = "000" THEN 
FindLabel = "#" & [SUPP_NO] & VBNewLine & [Fuse_Count]"

Answer 1

You need to add an EndIf to your function and you must have the [Fuse_Count] in your first line. Give this a try:

Function FindLabel ( [SUPP_NO], [SUPP_SUFF], [FUSE_COUNT] )
   if [SUPP_SUFF] = "000" then
       FindLabel = "#" & [SUPP_NO] & vbnewline & [FUSE_COUNT]
   end if
End Function

Answer 2

Function FindLabel ( [No], [Instructio] , [Y], [X] )
  FindLabel = [No] &vbnewline & " " &  [Instructio] &vbnewline &  "Y   "  &  [Y] & "  X  " & [X] 
End Function
