12.1.3 Payment Format with Text output

My client is using EDGE software for printing checks out of 11.5.10.2. The bank setup in Oracle 11i has a Payment Document which uses the seeded Payment Format "Short Check Format". When they run a payment batch, Oracle produces an output from the Format program, which they open in Internet Explorer. This output is in Text format. They save the output in Text format to a pre-determined directory. Then they open EDGE and provide it the file name from Oracle. EDGE prints out the checks. This process has been working fine for years.

No they are upgrading to 12.1.3. Firstly I do not see any Payment format in 12.1.3 which is equivalent to "Short Check Format". In my PPP I assigned "External Check Format" but it generates the output in PDF, not Text format.
