The SLEEP function suspends execution for the number of seconds you specify as its input argument.
This function is most useful in Dialogue Manager when you need to wait to start a specific procedure. For example, you can start a FOCUS Database Server and wait until the server is started before initiating a client application.
Is the number of seconds to delay execution. The number can be specified down to the millisecond.
Is the name of a field or a format enclosed in single quotation marks. The value returned is the same value you specify for delay.
The following example computes the current date and time, suspends execution for 4 seconds, and computes the current date and time after the delay:
TABLE FILE VIDEOTRK PRINT TRANSDATE NOPRINT COMPUTE START_TIME/HYYMDSa = HGETC(8, START_TIME); DELAY/I2 = SLEEP(4.0, 'I2'); END_TIME/HYYMDSa = HGETC(8, END_TIME); IF RECORDLIMIT EQ 1 END
The output is:
START_TIME DELAY END_TIME ---------- ----- -------- 2007/10/26 5:04:36pm 4 2007/10/26 5:04:40pm
