ViewPoint Installation Considerations
Call Errors
When paging from screen to screen within the VHS Browser, you might encounter this
event message:
ZPWY-ERR-TCP-STACKOVERFLOW (3016)
When this happens, one of the these call error messages displays:
program-name
specifies the name of the invoked SCREEN COBOL program if you were trying to
enter a screen, or the name of the current SCREEN COBOL program you were in.
VHS-error-number-1
specifies a VHS message error number. For an explanation of VHS errors, see
Appendix F, VHS Browser Messages.
VHS-error-number-2
specifies a VHS message error number. For an explanation of VHS errors, see
Appendix F, VHS Browser Messages.
The number following the VHS-error-number-1 or VHS-error-number-2 fields
(0016) is an error code returned by SCREEN COBOL, designating a terminal stack
space overflow. This means that the ViewPoint TCP requires more data space than is
configured. To resolve this problem, modify the PATHCONF file and set the TCP
MAXTERMDATA parameter to at least 64000 bytes. You must first stop the TCP:
SET TCP MAXTERMDATA 64000
After this is done, restart the TCP.
No EXTRAS Screen Available
If you do not have a ZVPT-EXTRAS ViewPoint Extras screen, you will not be able to
access the VHS Browser. When trying to enter the ViewPoint Extras screen, you get
this error message:
No EXTRAS screen is available. 0025
To resolve this situation, reinstall the ZVPT-EXTRAS program or modify your code. For
more information, see Merging VHS Browser With Your ZVPT-EXTRAS Requester on
page 2-19.
