{═════════════════════════════ USAGE.PAS ═════════════════════════════}

(*══════════════════════════════ NOTES ═══════════════════════════════*

 This file contains one or more examples of each 8086 instruction
 mnemonic with a variety of combinations of operand types.  It is not
 intended as a replacement for a tutorial or reference on assembly
 language programming, however in some cases a couple of examples
 of typical instruction syntax is all that you may need.  Please see
 the  various .PAS files (on the registration disk or in the archive
 TP-ASM.ZIP) for examples of assembly language in the context of
 working programs.


 The following symbols, used in the example instructions, can
 represent a variety of Pascal and/or Assembly symbols as indicated
 in the discussion which follows:

   Immediate_Byte   Immediate_Word
   MemoryVar_Byte   MemoryVar_Word   MemoryVarDWord   MemoryVariable
   MemoryReg_Byte   MemoryReg_Word
   CodeLabelSHORT   CodeLabel_NEAR


 Immediate_Byte can be:
  a standard Pascal Constant, an Assembly EQU Constant, or a numeric
  value or expression in the range -128 to 255

 Immediate_Word can be:
  a standard Pascal Constant, an Assembly EQU Constant, or a numeric
  value or expression in the range -32768 to 65535

 MemoryVar_Byte can be:
  a Pascal BOOLEAN, BYTE, CHAR, or SHORTINT Variable or Typed Constant
  or an Assembly BYTE Variable defined via DB or EQU B [..]

 MemoryReg_Byte can be:
  a MemoryVar_Byte or a Byte register (Al, Ah, Bl, Bh, Cl, Ch, Dl, Dh)

 MemoryVar_Word can be:
  a Pascal INTEGER or WORD Variable or Typed Constant
  or an Assembly WORD Variable defined via DW or EQU W [..]

 MemoryReg_Word can be:
  a MemoryVar_Word or a Word register (Ax, Bx, Cx, Dx, Si, Di, Bp, Sp)

 MemoryVarDWord can be:
  a Pascal LONGINT or POINTER (^INTEGER, ^BYTE, etc) Variable or Typed
  Constant, a Proc/Function VAR or UNTYPED Parameter,
  or an Assembly DWORD Variable defined via DD or EQU D [..]

 MemoryVariable can be:
  a MemoryVar_Byte, MemoryVar_Word, or MemoryVarDWord,
  or a Pascal Variable of any other Type (e.g. STRING)

 CodeLabelSHORT must be:
  an Assembly Code Label within 127 bytes (forward) or 128 bytes (back)
  from the beginning of the next instruction

 CodeLabel_NEAR must be:
  an Assembly Code Label within the current Assemble/Internal statement

 Dh is used as a typical Byte register.  It can be replaced by any of
  the following Byte registers:  Al, Ah, Bl, Bh, Cl, Ch, Dl, or Dh

 Si is used as a typical Word register.  It can be replaced by any of
  the following Word registers:  Ax, Bx, Cx, Dx, Si, Di, Bp, or Sp


 The following list contains separate examples for instructions using
 the Accumulator (AL or AX) in cases where the Accumulator version uses
 a different opcode.  Instructions using the Accumulator are often one
 byte shorter than instructions using another register.
