[Oorexx-devel] Parse

[Walter P. <pa...@ch...>]

Looking up Parse In the Language Reference, I noticed 2 Doc Problems:

The sybtax diagram does not allow for Parse Caseless Upper ... which is accepted by the Interpreter
>>-PARSE--+---------+-------+--------------------+------------------------------->
                     +-UPPER-+    +-CASELESS-+
                     +-LOWER-+
                 >--+-ARG-------------------------+--+---------------+--;-------><  etc.

In the text 
If you specify UPPER, the strings to be parsed are translated to uppercase before parsing.
If you specify LOWER, the strings are translated to lowercase.
Otherwise no translation takes place 

strings are should ne replaced by string 
(only one string is parsed)

And a minor problem with the error message for
Parse lower upper Var (which is, of course, wrong) 

    17 *-* Parse lower  upper   Var s l1 '+' l2  ;
Error 25 running H:\part.rex line 17:  Invalid subkeyword found
Error 25.12:  PARSE must be followed by one of the keywords ARG, LINEIN,
                        PULL, SOURCE, VALUE, VAR, or VERSION; found "UPPER"
