- { DR> DEL/ERASE command is able to erase an entire directory by using DEL *.*
- DR> With such speed. It clearly has a method other than deleting File by
- DR> File.

- Function $41 of Int $21 will do what you want. You'll need to
- make an ASCIIZ Filename of the path and File(s), and set a Pointer
- to it in DS:DX. When it returns, if the carry flag (CF) is set,
- then AX holds the Dos error code.
- }
- Function DosDelete (FileName : PathStr) : Word; {returns error if any}
- Var Regs : Registers;
- begin
- FileName[65] := 0; {make asciiz- maybe, not sure}
- Regs.DS := Seg(FileName); {segment to String}
- Regs.DX := offset(FileName)+1; {add one since f[0] is length}
- Regs.AH := $41;
- Regs.AL := 0; {Initialize}
- Intr ($21, Regs);
- if Regs.AL <> 0 {error} then DosDelete := Regs.AX else DosDelete := 0;
- end;
