/***********************************************************************/
/* Description: REXX macro to match pairs of keywords */
/* Syntax: match */
/* Notes: This macro will mark a line block enclosing all lines */
/* that are enclosed by a matching pair of keywords. */
/* Keywords can actually be more than 1 word, like */
/* 'end if' but are specified as 1 word. */
/* Supported keyword pairs are: */
/* #if - #endif */
/* begin - end; */
/* do - end */
/* if - endif */
/* loop - endloop */
/* \begin{ - \end{ (added by A. Pool) */
/* Bugs: Only keywords that START a line are considered for */
/* matching and each keyword must be on separate lines. */
