===== pdflg -- Paradigm flag (Mode argument to Realtime command) =====
PDFLG is an integer parameter that controls global real-time paradigm execution options. Showplay uses PDFLG as the MODE argument to the [[jvs:cigal:manual:chapter2:realtime|REALTIME]] command using the command line:
  realtime rtime.tmp runlog pdflg
RTIME.TMP is the [[jvs:cigal:manual:chapter1:rtprogram|real-time program file]] generated by Showplay based on your task options, and RUNLOG is the real-time log table that will be used to record the sequence and timing of events that occur during execution of the program.

PDFLG is a bit flag, where the binary bits have the following meanings (combine by addition):
        0 - execute RT program normally (default).
        1 - check for run-time errors
        2 - turn off taskbar explicitly during realtime 
            (Note: sometimes taskbar acts odd when it comes back.)
        4 - execute RT program normally, except that after each operation has completed 
            the amount of time the operation took is stored in the EXEC_FLAG field of the RUNLOG.  
            (Note: elapsed time only includes the time it takes from the scheduled execution time 
             until the operation completes and does not include any time spent setting up the 
             operation before its scheduled start time.
       10o - execute RT program and record elapsed times, but ignoring the scheduled execution times. 
             Each operation begins as soon as the previous operation is completed.  In this case 
             the elapsed time recorded is the total execution time required for the operation.
       20o - single step through realtime program
       40o - log every real-time event (normally on flagged events)
      100o - test for timing conflicts
      200o - Showplay test flag -- don't complain if a stimulus image file is not found 
     2000o - Use DirectDraw for display
