PA_UpdateProcessVariable (pNum)
| Parameter | Type | Description | |
| pNum | long |  | Process number to update |
Description
The routine PA_UpdateProcessVariable tells the (4D created) process number pNum to perform an outside call execution cycle of the form method for the form that is currently displayed.
If -1 is passed fNum, calling this entry point provokes the on screen update of all interprocess variables displayed in all open Forms (for use, not design) for all executing processes.
PA_UpdateProcessVariable is equivalent to the 4D command CALL PROCESS. For more information, refer to the 4th Dimension Language Reference manual.
If interprocess communication is required between several external processes the 4D extension should use a method based on private data or based upon the entry point PA_PostEvent.
Example
Force 4D to update all interprocess variables in every currently displayed form.
PA_UpdateInterprocessVariables(-1);
