Q

Extracting a substring from a variable position in a string

I would like to know how to search a variable length field (this is a sample of the field - /TRAK ADF/LQ QC/UNN1 3143). I would be searching for 'UNN1' within this field, and it can be anywhere within the field. Once it is located, I need the next five characters after it.
