BLINKER ENVIRONMENT NAME
------------------------------------------------------------------------------
Purpose : Specify the name of the environment variable for
Blinker run time options
Syntax : BLINKER ENVIRONMENT NAME <name>
Default : BLINKER
Example : #Rename the Blinker variable
BLINKER ENVIRONMENT NAME Testapp
and use the following command at the DOS prompt:
SET TESTAPP=/OO30
to alter the OPSIZE at program runtime without having to relink.
This command is used to change the name of the BLINKER environment
variable.
At program runtime the Blinker overlay manager checks the DOS
environment for the BLINKER environment variable, and if this is present
then the variable is examined for certain runtime parameters.
Following linking with the above command, the overlay manager will check
the environment for the TESTAPP variable, and if present, this variable
will be checked for the following parameters:
/CEnnn,nn (Amount of EMS to use for overlay cache)
/CXnnn,nn (Amount of XMS to use for overlay cache)
/DHn (Debug Handle)
/OOnnn (Overlay pool Operating size in kb)
/OU0 (Disable use of XMS UMBs for overlays)
/OU1 (Enable use of XMS UMBs for overlays)
/OP0 (Disable use of pageframe for overlays)
/OP1 (Enable use of pageframe for overlays)
The /CEnnn,nn setting is an override of the link-time command BLINKER
CACHE EMS nnn which controls the amount of EMS memory used by the
overlay manager for overlay caching. For details of the usage of these
values, see the command BLINKER CACHE EMS in chapter 6.
The /CXnnn,nn setting is an override of the link-time command BLINKER
CACHE XMS nnn which controls the amount of XMS memory used by the
overlay manager for overlay caching. For details of the usage of these
values, see the command BLINKER CACHE XMS in chapter 6.
The /DHn setting is an override of the link-time command BLINKER DEBUG
HANDLE n which controls the handle of the destination of debug output
from Blinker. For details of the usage of this value, see the command
BLINKER DEBUG HANDLE.
The /OOnnn setting is an override of the link-time command BLINKER
OVERLAY OPSIZE nnn which controls the operating size of the Blinker
overlay pool. For details of the usage of this value, see the command
BLINKER OVERLAY OPSIZE.
The /OUn setting (where n=0 is disabled, and n=1 is enabled) is an
override of the link-time command BLINKER OVERLAY UMB which controls the
allocation of the overlay pool using XMS 2.0 upper memory blocks. For
details of the usage of this value see the command BLINKER OVERLAY UMB.
The /OPn setting (where n=0 is disabled, and n=1 is enabled) is an
override of the link-time command BLINKER OVERLAY PAGEFRAME which
controls the allocation of the overlay pool using the EMS (3.2+)
pageframe. For details of the usage of this value see the command
BLINKER OVERLAY PAGEFRAME.
