cputime, tstart, tstop

cputime(onoff)

:: Stop displaying cputime if its argument is 0, otherwise start displaying cputime after every top level evaluation of Asir command.

tstart()

:: Resets and starts timer for CPU time and GC time.

tstop()

:: Stops timer and then displays CPU time GC time elapsed from the last time when timer was started.

return

0

onoff

flag (arbitrary)

• Command cputime() with NON-ZERO argument enables Asir to display CPU time and GC time after every evaluation of top level Asir command. The command with argument 0 disables displaying them.
• Command tstart() starts measuring CPU time and GC time without arguments. The parentheses `()' may be omitted.
• Command tstop() stops measuring CPU time and GC time and displays them without arguments. The parentheses `()' may be omitted.
• Command cputime(onoff) has same meaning as ctrl("cputime",onoff).
• Nested use of tstart() and tstop() is not expected. If such an effect is desired, use time().
• On and off states by cputime() have effects only to displaying mode. Time for evaluation of every top level statement is always measured. Therefore, even after a computation has already started, you can let Asir display the timings, whenever you enter the debug-mode and execute cputime(1).
