Using PARAM SWAPVOL
The SCREEN COBOL compiler recognizes the SAMECPU parameter passed in the
command interpreter PARAM command. The format of the command is:
number
is any nonzero number. A 0 disables SAMECPU.
number does not designate which CPU the processes run in; that is controlled by
the CPU run option.
The command sequence to run processes in the same CPU is:
TACL 1> PARAM SAMECPU 1
TACL 2> SCOBOLX/IN ... , OUT ...
Using PARAM SWAPVOL
The command interpreter SWAPVOL parameter specifies a swap volume on which:
•
SCOBOLX and SCOBOLX2 create their temporary work files
•
SCOBOLX2 creates its process swap disk volume, which contains the run-time data
stack swap file for the SCOBOLX2 process
The SCREEN COBOL compiler recognizes the SWAPVOL parameter passed in the
command interpreter PARAM command. The format of the command is:
$volume
specifies a disk volume other than the current one.
If you do not specify PARAM SWAPVOL, all temporary work files for both SCOBOLX
and SCOBOLX2 are created in the same subvolume where the SCOBOLX object
program file resides, unless the current swap volume has been specified in a TACL SET
SWAP command. System performance might be adversely affected if the SCOBOLX
object program file resides on $SYSTEM and the process swap files are created in the
same subvolume as that of the SCOBOLX object program file.
For example, the command sequence to specify $MINT as the disk volume on which
temporary work files reside is:
TACL 3> PARAM SWAPVOL $MINT
PARAM SAMECPU number
PARAM SWAPVOL $volume
Note. The SWAP option of the SCOBOLX run command does not affect where the temporary
work files for SCOBOLX and SCOBOLX2 are created, but it does affect where the Kernel
Managed Swap Facility (KMSF) creates the run-time data stack swap file to be used by the
SCOBOLX process.
