Introduction: RCheck performs syntax checks on RCode programs.  It's especially useful for screening hand-written RCode prior to lengthy downloads to AIBO, since waiting several minutes to discover a mistake is... annoying. It looks for invalid keywords, incorrect usage of keywords, missing or extraneous parameters, missing labels, incomplete or invalid WHILE/WEND, FOR/NEXT, REPEAT/UNTIL, DO/LOOP statements. RCheck also warns about uninitialized variables being used (a common typo), and optionally looks for RCode labels or variables which are identical except for case.  Usage:

	RCHECK  [options]  target1.r  [target2.r ...]

The command line options are:

-EXPR	Support extended syntax implemented in ReCode compiler.
-LABELS	Flag as error labels which differ only by case.  ie:  Trying to use similar labels names 'G_MAX', and 'G_Max' at once would be considered an error.  RCode permits such label names, but it is poor coding style, and can create difficult to debug problems (when you get them mixed up).
-VARS	Flag as errors variables which differ only by case.  ie:  Trying to use variable names 'AAA', 'Aaa', 'aaa' all at once would be considered an error.  RCode permits such variable names, but it is poor coding style, and can create difficult to debug problems (when you get them mixed up).
