The Question is:

 
I am getting the error below when excectuing a program. How can this be resolved?
 
%SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=00001B40,

The Answer is :

 
  Please see HELP/MESSAGE ACCVIO for information on the specific
  meaning and contents of the ACCVIO error -- extensive details
  of the Access Violation are provided with the ACCVIO error.
 
  Based on the presence of hexidecimal 20 byte in R0, in the failing
  program counter, and elsewhere, it would appear that critical data
  on the program stack has been overwritten with space characters.
 
  Please see topics (819), (837), (1246), (2223), (2234), (3215),
  (5533), and very likely other topics here in Ask The Wizard.
 
  Please contact (or continue to work with) the application vendor(s),
  as source code access is normally required when debugging access
  violation errors -- ignoring any approach involving the rather
  extensive effort involved in reverse-engineering (if such effort
  is permitted or prohibited by applicable software licenses and by
  applicable legal requirements, such as the DMCA in the US) the
  application binaries involved, of course.
