Summary
NOTE: This procedure is supported for compatibility with previous software and should not be
used for new development.
The ALTERPRIORITY procedure is used to change the execution priority of a process or process
pair.
A process or process pair has two priority values: the initial priority value and the current priority
value. ALTERPRIORITY changes both priority values to the specified value.
Syntax for C Programmers
This procedure does not have a C syntax, because it is superseded and should not be used for
new development. This procedure is supported only for compatibility with previous software.
Syntax for TAL Programmers
CALL ALTERPRIORITY ( process-id ! i
,priority ); ! i
Parameters
process-id
input
INT:ref:4
is a four-word array containing the process ID of the process whose execution priority is to be
changed, where:
Process name or creation timestamp[0:2]
Reserved.<0:3>[3]
Processor number where the process is executing.<4:7>
PIN assigned by the operating system to identify the process in the processor.<8:15>
If process-id[0:2] references a process pair and process-id[3] is specified as -1, then
the call applies to both members of the process pair.
priority
input
INT:value
is a new execution priority value in the range of {1:199} for process-id.
