PBMake includes an option to override the default compiler, the
      source extension and the object extension, if the defaults are not
      correct for the compiler you need a make engine for.

      If you do not use these three added directives, they default to:

      COMPILER=CLIPPER
      SRCEXT=.PRG
      OBJEXT=.OBJ

      You may also override the COMPILER=, SRCEXT=, OBJEXT=, OBJDIR= and
      SRCDIR= which are active across all sections with individual
      directives for each section.

      So, you can do this:

      FLAG= /N /M /A /V /W /ES2
      INCLUDE= MASTER.CH COMM.CH
      SRCEXT=.PRG   (this is a default, anyway)
      OBJEXT=.OBJ   (this one too)

      PROG1= HELP MAIN MENU

      FLAG2= /M
      PROG2= OLDSTUFF

      FLAG4=
      COMPILER4=MASM
      SRCEXT4=.ASM

      INCLUDE5= myheader.h
      FLAG5=
      COMPILER5=CL /c /AL /Zl /W2 /FPa /Gs
      SRCEXT5=.C

      FLAG6= -E -= -MC -^2
      COMPILER6=FOOBAR
      SRCEXT6=.FOO
      OBJEXT6=.BAR
      OBJDIR6= OUTPUT%\DATA\FOO\BAR

      Note: When you specify an OBJDIR, and the compiler is not
      CLIPPER for that area, the output directory will not be verified.
      This is done so that you may use whatever compiler directive that
      is necessary to cause the output to be placed in some other
      directory, without regard for making the OBJDIR??= directive look
      like a findable directory to DOS.

      For example, in the example above, there is no way to validate
      OUTPUT%\DATA\FOO\BAR with a DOS path validation.
