; This example shows how to use the file loader segment, just give it a
; filename string, drive number, data pointer and mfm buffer and it'll
; load it to your data point... If the file DOESNT Exist, your okay, it
; just returns with nowt.
;
; NOTE: this routine cannot handle directories yet!!! (i'll have it sorted)
; (top one.) so just keep everything on a disk, besides, directories take
; up sector space!! oh, and it only recognises old file sys, i'll have
; fastfilesys sorted 4 all you 2.0 owners.. (more disk-space and less
; fucking about..)
; Oh, and disk drives ONLY please!
