Troubleshooting


This section contains hints for some REXX errors, symptoms, and messages. 
Note that a lot of hints in this section are captured from CompuServe 
messages. 
In addition to the tips mentioned below I suggest everyone having problems 
with REXX programs should get the new Object-Oriented REXX. 
Object-Oriented REXX has much more descriptive error messages and the 
documentation is better than the normal REXX online documentation. 
Another good source for Troubleshooting information is the Common REXX 
Pitfalls page on the home page of Quercus Systems (see Internet - Web 
Pages) 
Note that the information related to various APARs is included in the 
sections General hints for REXX, REXXUTIL functions and Change the WPS 
with REXX. See those sections for additionanl information.
