   This module provides functions that
   1) generate a C module for a given parse table
   2) unload a parse table to a binary image file
   3) load a parse table from a binary image file.

C-Module 

void PLR_CTab_Source(FILE* fp, c_string fid, PLR_Tab PTab)
 writes source for parse table 'PTab' to file 'fp';
produces a source header if filename 'fid' is not empty

void PLR_CTab_Modul(c_string Environ, PLR_Tab PTab, c_bool shortform)
#define PLR_printCTab PLR_CTab_Modul
 creates source [$'Environ'/]<Language>_pim.c for parse table 'PTab' 
void PLR_Src_Source(FILE* fp, c_string fid, PLR_Tab PTab)
 writes source for parse table 'PTab' to file 'fp';
produces a source header if filename 'fid' is not empty

void PLR_Src_Modul(c_string Environ, PLR_Tab PTab)
#define PLR_printCTab PLR_CTab_Modul
 creates source [$'Environ'/]<Language>.ptbl for parse table 'PTab'

Binary Image 

void PLR_fputTab_bin(BinImg_T img, PLR_Tab PTab)
 unloads parse table 'PTab'
to binary image 'img' (reentrant)

void PLR_putTab_bin(PLR_Tab PTab)
 unloads parse table 'PTab'
to the current ( previously opened ) image

void PLR_putTab(c_string Environ, PLR_Tab PTab)
 unloads parse table 'PTab' to image [$'Environ'/]<Language>.pim 
PLR_Tab PLR_fgetTab_bin(BinImg_T img)
 loads a parse table
from binary image 'img' (reentrant)

PLR_Tab PLR_getTab_bin(void)
 loads a parse table
from the current ( previously opened ) image

PLR_Tab PLR_getTab(c_string Language)
 loads a parse table named 'Language'
from image [$PATH/]<Language>.pim

PLR_Tab PLR_getTab_env(c_string Environ, c_string Language)
 loads a parse table named 'Language'
from image [$'Environ'/]<Language>.pim

PLR_Tab PLR_getETab(Any_T Environ, c_string Language)
 like PLR_getTab / PLR_getTab_env;
can be used as embedded language parser contructor
( see function 'PT_setEParser' )
