The %wait() function returns the exit code of the child processes created by the current process.
For Windows: Not Supported
var = %wait(&status)
The status is returned in the integer status, passed by its address.
Note that even though status is an integer, only the lower 16 bits are updated by the system call. See the UNIX system documentation for more details on the format of the returned status.
status=0 (void)%wait(&status) high$status=int(status/256) low$status=mod(status,256) begin case case low$status=255 * Child stopped due to a signal case low$status=0 * Child stopped by calling exit() case high$status=0 * Child was terminated due to a signal end case
