  10 /* notes: I have tried to make this correspond to the IEEE version
  11  * of the standard, specifically the primary ASCII version.  It should
  12  * be trivial to create the binary version given this source (which is
  13  * one of MANY things that have to be done to make this correspond to
  14  * the hp-microtek version of the standard).
  15  *
  16  * 16-bit support is assumed to use 24-bit addresses
  17  * The linker can sort out segmentation-specific stuff
  18  * if it keeps track of externals
  19  * in terms of being relative to section bases
  20  *
  21  * A non-standard variable type, the 'Yn' variable, has been introduced.
  22  * Basically it is a reference to extern 'n'- denoting the low limit
  23  * (L-variable) of the section that extern 'n' is defined in.  Like the
  24  * x variable, there may be no explicit assignment to it, it is derived
  25  * from the public definition corresponding to the extern name.  This
  26  * is required because the one thing the mufom guys forgot to do well was
  27  * take into account segmented architectures.
  28  *
  29  * I use comment classes for various things and these are undefined by
  30  * the standard.
  31  *
  32  * Debug info should be considered totally non-standard (local labels are
  33  * standard but linenum records are not covered by the standard.
  34  * Type defs have the standard format but absolute meanings for ordinal
  35  * types are not covered by the standard.)
