How to Write Multiple Device=
lines into System.ini

Keywords: system.ini device= 

This example writes multiple device= lines to the SYSTEM.INI. It is *very* fast.

NewDevice1 = "DEVICE=COOLone.386"
NewDevice2 = "DEVICE=COOLtwo.386"
NewDevice3 = "DEVICE=COOLthree.386"

        if x==1 then sysname="system.ini"

        ; Obtain filesize and allocate binary buffers
        fs1=FileSize(sysname)
        srcbuf  = BinaryAlloc(fs1)
        editbuf = BinaryAlloc(fs1+100)
