There's a text field that contains hydrologic codes for soils. Most are in a single letter format (A). Some however are deliniated for multiple hydrologic codes (A/B). I'd like to use VBA to parse the codes character by character to in a field calculation.
I'm having trouble programing a loop into a field caculator. Is there a way to do this?
