Import Format script required to work across multiple fields

Question

I am currently constructing an Import Format, and using datapump import scripts on several of the fields to implement specific logic based on the values present. For example:
Function TBNetwork(strField, strRecord)
If Left(strField, 1) = "N" Then
TBNetwork = strField
Else
TBNetwork = "Network N/A"
End If
End Function
However, I need this to also evaluate the values across other fields too, but the default two inputs for the function are strField and strRecord.
How can I achieve this? Can I declare new variables and define as follows?
Dim strCustomer = varValues(23)
Or do I need to look at implementing a different type of script? Any suggestions would be greatly appreciated!

Answer 1

strRecord represents the entire data line from your source file that is currently being processed. You can parse this to get any of the values from your data line to use/evaluate in your script. There is an accelarator script DW.Utilities.fParseString which will do the string parsing for you. As you probably know strField only returns the field from the data file that you have specified in your import format for the associated dimension.
