* This file contains definitions for all the constants and structures
* needed to use the intermediate code files generated and read by
* the Portable C Compiler and related compilers.
* Rules for changing this code:
* 1) All op values must be integer constants -- this permits us to run
* a 'sed' script on this file to create %term declarations for yacc.
* 2) Because the PCC uses fancy ASG and UNARY macros, assignment
* operators must have values 1 greater than corresponding normal
* operators, and unary operators must have values 2 greater ditto.
* 3) Ops used only by f1 must have values >= 150 (PCCF_FORTOPS).
* 4) Other language-dependent ops must have values >= 200.
