Appendix CEnvironment Variables
C.2.8 SNALU1MPP
The 3270 emulation program uses SNALU1MPP to specify the maximum print position (line length) for 3270 printer
sessions for LU 1 printing and LU 3 unformatted printing. If SNALU1MPP is not set, the program uses the default
value 132.
For more details, refer to the information about controlling printer sessions in
HP-UX SNAplus2 3270 User’s Guide.
C.2.9 SNAMSG
The 3270 emulation program uses SNAMSG to control tracing on data flowing between the program and the SNAplus2
node.
For more details, refer to the information about controlling tracing on user-space components in HP-UX SNAplus2
Diagnostics Guide.
C.2.10 SNAP3270_COLOR
HLLAPI applications can support color even if the 3270 emulator is started on a monochrome terminal. To allow
HLLAPI applications to support color, set the SNAP3270_COLOR environment variable to 1 (one) to force the
3270 emulation program to respond that color is supported in response to a Read Partition Query from the host .
C.2.11 SNAPRMPL
The 3270 emulation program uses SNAPRMPL to specify the maximum page length (number of lines on a page)
for 3270 printer sessions. If SNAPRMPL is not set, the program uses the default value 60.
For more details, refer to the information about controlling printer sessions in HP-UX SNAplus2 3270 User’s Guide.
C.3 Environment Variables That Affect RJE Workstations
C.3.1 SNABLANKSCREEN
The RJE console program uses SNABLANKSCREEN to specify the terminal type. For most terminals, there is no
requirement to set SNABLANKSCREEN.
On some terminals, particularly when the background screen color is not black, you may find that blank areas of
the RJE console screen background are not being cleared correctly. In this case, set SNABLANKSCREEN to BW
for a monochrome black-on-white terminal, or STD (standard) for any other terminal type. There is no need to set
SNABLANKSCREEN if the screen background is displayed correctly without setting it.
For more details, refer to the information about screen clearing on different terminal types for the RJE console
program in HP-UX SNAplus2 RJE User’s Guide.
C.3.2 SNAMSG
The RJE workstation uses SNAMSG to control tracing on data flowing between the program and the SNAplus2 node.
For more details, refer to the information about controlling tracing on user-space components in HP-UX SNAplus2
Diagnostics Guide.
