And where is the value of filei supposed to be coming from?

Search the forum for running Rexx programs in batch.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

So have you looked in the manual to see how you get your parm (clue: argument) into your program?

And, have you looked through the forum to find the examples that are in here?

Ok, to get you started.
The JCL parm should have the datasetname i.e. PARM='%LISTDS SYS1.HELP'
In your program after the first line you should have FILEI="'"translate(arg(1))"'"
The assignment of 'filei' from the parm field can be done in many ways, the above is just one. Note that it put quotes around the argument, those are required for the LISTDS command. Also note the percentage sign in the parm field. In my opinion it is bad practice to have a REXX (or CLIST for that matter) with the same name as a program, but the percentage sign tells the interpreter that the name in the parm field is a REXX or CLIST.

in that case you can use the LISTDSI function to get the dsname, i.e.:
cc=ListDsi('filei file')
filei="'"sysdsname"'"

refer to the REXX manual for details.
