Hello John,

Many of these programs are listed in the Diagnostic Aids manual.  However, a 
machine check in 
IBM code is generally an APARable situation.

About the only time it is not an IBM problem is when your code is calling IBM 
code (such as an 
API) and you are not setting parameters etc correctly.  That doesn't appear to 
be the case 
here.  Call IBM support and send them the dump information.

MCH0601 indicates incrementing a pointer by too much and walking off the end of 
some allocated 
chunk of storage.  It is usually a programming problem.

What is the name of the space (the &1 value) when the MCH0601 message is sent?

Regards,
Simon Coulter.
