8.1.5 Command timeout timeout

The Open, Lock, Job, and Read commands employ an optional timeout specification, associated with the testing of an external condition.

If the optional timeout is absent, the command will proceed if the condition, associated with the definition of the command, is satisfied; otherwise, it will wait until the condition is satisfied and then proceed.

$Test will not be altered if the timeout is absent.

If the optional timeout is present, the value of numexpr must be non-negative. If it is negative, the value 0 is used. Numexpr denotes a t-second timeout, where t is the value of numexpr.

• If t = 0, the condition is tested. If it is true, $Test is set to 1; otherwise, $Test is set to 0. Execution proceeds without delay.
• If t is positive, execution is suspended until the condition is true, but in any case no longer than t seconds. If, at the time of resumption of execution, the condition is true, $Test is set to 1; otherwise, $Test is set to 0.
