As JShepherd notes, the TAL code indicates that the request and response messages are not simple text strings, but moderately complex structures. Your coworker had some instructions about how to construct and interpret those structures. If that coworker is still around, ask where he or she got the instructions. If he or she is not still around, you might find some documentation in a file in the subvolume $DATA02.ACIUTILS, or in some other location that contains files from ACI. If you are lucky, ACI provided some documentation and the structure declarations suitable for writing the program in C. If they supplied only help for TAL programmers, you will have a bit of a difficult time if you don't know TAL.
