Module Name:
  IfrOpCodeCreation.c

Abstract:

  Library Routines to create IFR independent of string data - assume tokens already exist
  Primarily to be used for exporting op-codes at a label in pre-defined forms.

Routine Description:

  Create a SubTitle opcode independent of string creation
  This is used primarily by users who need to create just one particular valid op-code and the string

  location to pre-defined forms in HII)
