I know you can update the batch COBOL parameters of a job and run a job which contains a batch COBOL program in IPA. I was asked if you could run a batch COBOL program and supply the parameters.
I am not real sure I totally understand your question, but I have used a Cobol program, outside of IPA, to update and then submit another form, i.e. AR130. I have also used IPA to modify the parameters of AR130 and then submit the AR130. Is this what you are asking?
