Have a look at the code behind CRTCSVDTA, one of my open source utilities. 
That dynamically processes fields from a file by reading from a program 
described file and extracting data from the record based on info from the 
list fields API. It should be do-able to reverse the process and write to 
a file using arrays to hold the field names and values. The RPGLE code 
can be seen here:
http://dbg400.homeip.net/cgi-bin/viewcvs.cgi/dbg400/QRPGLESRC/DBG201R4.rpgle?view=markup
and the whole utility from http://www.dbg400.net/crtcsv.html

Whether it's any quicker or not is debateable, but I think it is feasible.
