passing multivalues into python using arcpy.Get ParameterAsText

Question

Howdy All~

I've found a couple ESRI examples where they show how you can pass multivalues into a script (arcpy.GetParameterAsText(0)) and then use .split(";") to split the value list. When I try it python doesn't split on the ";" it splits every single character in the list. I've tried changing split characters and get the exact same result. Below is a sample of my test script where I have input 2 files, it prints out the list showing both files separated by a ";" and then prints each split out value:

InASCIIList = arcpy.GetParameterAsText(0)
arcpy.AddMessage ("InASCIIList is " + InASCIIList)
InASCII = InASCIIList.split(";")
for InASCII in InASCIIList:
      arcpy.AddMessage ("InASCII is " + InASCII)

and here's what prints out:
Executing: listtest D: \TEST\script	estasc\month11_7450p.asc;D:\TEST\script	estasc\month10_7450p.asc D: \TEST\script\OutputFolder

James, you're awesome! I knew I had to be missing a step somewhere.
Thanks for your help.

InASCIIList = arcpy.GetParameterAsText(0)
arcpy.AddMessage ("InASCIIList is " + InASCIIList)
InASCII = InASCIIList.split(";")
for InASCII in InASCIIList:
      arcpy.AddMessage ("InASCII is " + InASCII)

You split the string InASCIIList into a list called InASCII with the split() method, but then iterate through the string InASCIIList instead of the list InASCII.  Try this:

InASCIIString = arcpy.GetParameterAsText(0)
arcpy.AddMessage ("InASCIIString is " + InASCIIString)
InASCIIList = InASCIIString.split(";")
for InASCII in InASCIIList:
      arcpy.AddMessage ("InASCII is " + InASCII)
