Message: ADM0275 E GRAPHICS CANNOT BE SHOWN REASON CODE n
Several factors can cause this GDDM error message when attempting to display
graphics. Check each of the following items carefully in the order listed
and take corrective action:
The host (VTAM) logmode you are using must be a queriable logmode. By default,
your host LU is assigned a logmode which defines screen size and queriability
features. If you have a nonqueriable logmode, then graphics cannot be displayed.
Check with your VTAM systems programmer if you think your logmode is not
defined as queriable; tell them that the PSERVIC parameter must start with
‘028’ or ‘02C’.
If your host uses a session manager such as CA-Supersession or TPX, the
session manager must be configured such that device query is supported.
Otherwise, graphics cannot be displayed because all host graphics applications
will perform a device query before sending its graphics data.
Reason Codes for ADM0275 E message:
The host logmode does not support extended data stream. Contact the VTAM
systems programmer to have extended data stream turned on.
The query failed. Follow steps 1 through 2 listed above.
The graphics DLL is not in the application directory or in the path. You
should have received a warning that graphics were not available. For Windows
3.x, the file is WIN3179G.DLL, for Windows 95 and Windows NT, the file
The graph is displaying, but not in graphics mode - it is using alphanumeric
characters to approximate the picture.
This usually means there is a logmode problem. For some reason the host
application software thinks that the device cannot display graphics so
it sends alphanumeric data instead. Make sure the logmode is queriable
When displaying CA-TELLAGRAF, CA-DISSPLA or Boeing EIS graphics the screen
seems to have shrunk.
This condition occurs because the CA-TELLAGRAF, CA-DISSPLA, and Boeing
EIS graphics packages make internal adjustments when using a 3270 screen
size other than Mod 3 (32 x 80). Change the logmode to Mod 3 and try again
to obtain better results OR set the value of Resolution to TERMINAL instead
of HIGH in CONFIG.
SAS message: ADMASPT NOT FOUND
This commonly occurs in VM/CMS when you specify the GDDM79 device driver
but the GDDM TXTLIBs are not being accessed in the VM/CMS session. SAS
requires the GDDM TXTLIB’s ADMGLIB and ADMRLIB.
We recommend that the IBM3179 device driver be used in place of the GDDM79
device driver. Then the GDDM TXTLIBs are not necessary.
