You can also use WAIT to allow the screen to refresh before performing another task.

Example

Wait for 4.5 seconds between the times stored in TIME1 and TIME2, and then display those values in the LOG window:

time1 = datetime();
call wait( 4.5 );
time2 = datetime();
diff=putn((time2-time1),'4.1');
put time1= time2= diff=;

Take the last three digits before and after the decimal point from the two times: TIME1=872.229 and TIME2=876.749. Subtracting TIME2 from TIME1 results in 4.52 seconds total wait time.

time1=1069234872.22999
time2=1069234876.74999
diff=4.5

Create numeric text entry controls named START and FINISH and assign the format DATETIME20.2 to them. Enter the following program in the frame's SCL entry:

init:
   start.text=datetime();
   call wait(3.1);
   finish.text=datetime();
return;
