Acucobol-85 pre-processors

[BillV]

Does anyone have experience with compiler pre-processors in Acucobol? I've recently worked with Progress which has pretty powerful pre-processors built into the comiler. I've read in Acucobol's doc that we can write our own pre-processors. Are there any pre-processors available which I can use/buy without having to write them myself? I miss Progress's pre-processor variables & "ifdef"s.

Thanks,

Bill
