DOINTR IEXP1,IEXP2,IEXP3,IEXP4,IEXP5,IEXP6,IEXP7,IEXP8,IEXP9,IEXP10

 Function
  Generate system interrupt number IEXP1 (0-255) with the following
   register values:
    AX    = IEXP2
    BX    = IEXP3
    CX    = IEXP4
    DX    = IEXP5
    SI    = IEXP6
    DI    = IEXP7
    FLAGS = IEXP8
    DS    = IEXP9
    ES    = IEXP10

 Syntax
  DOINTR int,ax,bx,cx,dx,si,di,flags,ds,es

   int     - An integer expression with the interrupt number to call
             (0 through 255).
   others  - Integer expressions with 16-bit register values to pass to
             the interrupt (ax, bx, cx, dx, si, and di are general purpose
             registers; ds and es are segment registers; flags is the 80x86
             processor status register).

 Remarks
  This statement allows practically unlimited flexibility in PPL.  It
  allows you to access any system service available via the BIOS (video,
  disk, time, etc), DOS or other third party interface (DESQview, NETBIOS,
  IPX/SPX, Btrieve, etc).  The possibilities are limited only by your
  imagination.  Values that are returned via register may be accessed via
  the REG...() functions.  The values to pass to specific interrupts will
  vary by the interrupt and function desired.  WARNING!!!  DOINTR  can be
  a very valuable tool when used wisely; it can also be extremely
  destructive when used improperly (either accidentally or intentionally).
  Use it at your own risk!

 Examples
  ' Create subdirectory - DOS function 39h
  INTEGER addr
  STRING  path
  LET path = "C:\$TMPDIR$"
  VARADDR path,addr
  DOINTR 21h,39h,0,0,addr%00010000h,0,0,0,addr/00010000h,0
  IF (REGCF() & (REGAX() = 3)) THEN
   PRINTLN "Error:  Path not found"
  ELSE IF (REGCF() & (REGAX() = 5)) THEN
   PRINTLN "Error:  Access Denied"
  ELSE IF (REGCF()) THEN
   PRINTLN "Error:  Unknown Error"
  ELSE
   PRINTLN "Directory successfully created..."
