Error handling: errors.rex

This program resides in the tests directory. It depends on two files located in the bin/resources directory: rexxmsg.xml, which is part of the ooRexx source tree (you can find it at main/trunk/interpreter/messages), and revision, which contains the revision number of the rexxmsg.xml file.

The program executes the following tests:

1. Compare the version number contained in the revision file with the current ooRexx version number, and stop if they are not identical
2. Inspect the source files of the Rexx Parser, locate all the calls to the Syntax routine, and verify that the label and the arguments are the same, that they are integers, and that the message stored in the Parser is identical to the message stored in rexxmsg.xml.
3. For every syntax error that the parser is able to detect, run a program that produces exactly this error, and then compare the output produced by the ooRexx interpreter. Stop if the errors produced are not completely identical.

When errors.rex completes without errors, you can be sure that the syntax errors detected by the Rexx Parser are identical to the errors detected by (the current version of) the ooRexx interpreter.

To run errors.rex, change to the Rexx Parser directory, and run

tests\errors

under Windows, or

rexx tests/errors

under Linux.
