SLEEP

SLEEP function allows the program to pause execution for a specified period.

COMMAND SYNTAX

    SLEEP {expression}

SYNTAX ELEMENTS

expression may evaluate to one of two forms:

Numeric in which case the statement will sleep for the specified number of seconds or fractions of a second

"nn:nn{:nn}" in which case the statement will sleep until the time specified.

If expression is not supplied then a default period of 1 second is assumed.

NOTES

Sleeping until a specified time works by calculating the time between the current time and the time supplied and sleeping for that many seconds. If in the meantime the host clock is changed the program will not wake up at the desired time;

TAFJ note: sleeping until a specified time doesn't work.

If invoking the debugger while a program is sleeping and the execution continued, the user will be prompted:

     Continue with SLEEP (Y/N)?

If "N" is the response, the program will continue at the next statement after the SLEEP.

    * Sleep for two and a half seconds...
    SLEEP 2.5
