/* CFITSIO Lexical Parser */
/* */
/* This file is one of 3 files containing code which parses an */
/* arithmetic expression and evaluates it in the context of an input */
/* FITS file table extension. The CFITSIO lexical parser is divided */
/* into the following 3 parts/files: the CFITSIO "front-end", */
/* eval_f.c, contains the interface between the user/CFITSIO and the */
/* real core of the parser; the FLEX interpreter, eval_l.c, takes the */
/* input string and parses it into tokens and identifies the FITS */
/* information required to evaluate the expression (ie, keywords and */
/* columns); and, the BISON grammar and evaluation routines, eval_y.c, */
/* receives the FLEX output and determines and performs the actual */
/* operations. The files eval_l.c and eval_y.c are produced from */
/* running flex and bison on the files eval.l and eval.y, respectively. */
/* (flex and bison are available from any GNU archive: see www.gnu.org) */
/* */
/* The grammar rules, rather than evaluating the expression in situ, */
/* builds a tree, or Nodal, structure mapping out the order of */
/* operations and expression dependencies. This "compilation" process */
/* allows for much faster processing of multiple rows. This technique */
/* was developed by Uwe Lammers of the XMM Science Analysis System, */
/* although the CFITSIO implementation is entirely code original. */
/* */
/* */
/* Modification History: */
/* */
/* Kent Blackburn c1992 Original parser code developed for the */
/* FTOOLS software package, in particular, */
/* the fselect task. */
/* Kent Blackburn c1995 BIT column support added */
/* Peter D Wilson Feb 1998 Vector column support added */
/* Peter D Wilson May 1998 Ported to CFITSIO library. User */
/* interface routines written, in essence */
/* making fselect, fcalc, and maketime */
/* capabilities available to all tools */
/* via single function calls. */
/* Peter D Wilson Jun 1998 Major rewrite of parser core, so as to */
/* create a run-time evaluation tree, */
/* inspired by the work of Uwe Lammers, */
/* resulting in a speed increase of */
/* 10-100 times. */
/* Peter D Wilson Jul 1998 gtifilter(a,b,c,d) function added */
/* Peter D Wilson Aug 1998 regfilter(a,b,c,d) function added */
/* Peter D Wilson Jul 1999 Make parser fitsfile-independent, */
/* allowing a purely vector-based usage */
