REXX

Logic highlighting does not support a terminating semicolon in the IF expression, or a semicolon before the THEN or ELSE instructions.

In addition, IF statements which have the THEN keyword on the following line but do not have a continuation character at the end of the IF expression will cause highlighting errors.

For example, although these statements are valid in REXX, the ELSEs will be highlighted as a mismatched ELSEs:

     IF a=b; THEN say 'ok'; ELSE; say 'Not OK';
     IF a=b
          THEN say 'ok';
          ELSE say 'Not OK';
