I replaced the original Charlotte REXX filter (WW2PARSE) with one in Systems Programming C (WW2PARSC) in around 1996, both for performance and to add new function, but it's still a Pipeline filter, consisting of about 8600 lines of C source. That's certainly one way to implement a complex filter without impacting performance, although the initial learning curve was quite steep (especially as I hadn't written much C before). I haven't seen any other filters written in C. Jonathan Scott IBM Hursley, UK
