Description
The SPAWNPID() function returns the identity of the last spawned process. The process identity returned can be used with the ACTIVEPID() or the CANCELPID() functions. A spawned process will only remain active while the user remains logged in to the system. All spawned processes will be terminated when the user logs out. See the RUN command for batch processing.
Example
spawn db program m_activepid = spawnpid() if activepid(m->m_activepid) if cancelpid(m->m_activepid) dialog box "Process Canceled " else dialog box "Unable to Cancel Process." endif else dialog box "There is no Process Active". endif
