Starting New Processes
These conditions must be met before TACL can start a process at a high PIN:
•
The HIGHPIN option for the code file must be enabled at compile or bind time
•
Either the RUN /HIGHPIN ON/ option or the #HIGHPIN built-in variable (or both)
must be ON
•
There must be a high PIN available
Table 6-1 describes how TACL resolves each combination of HIGHPIN settings. A
dash (-) indicates that the option is not specified.
