   This file contains some valid (and invalid) statements in the 
   pattern script language. This can be used in conjuction with
   the pp executable and the 'asm.pp' assembler script, which is 
   responsible for parsing and compiling the current format.
   
   * http://bumble.sf.net/books/gh/gh.c  
      for the source code for the pp executable
   * http://bumble.sf.net/books/gh/asm.pp
      source code for the assembler script

   try: 
   >> pp -a asm.pp -i t.commands.pss
     This will run the program in interactive mode. Then type 'rr'
     to run the assembler on the commands to see if they parse 
     correctly. Hopefully soon (2019) it will be possible to type
   >> pp -f t.commands.pss  
     which will do the same thing.
