Function WaitPeriod() Foundation

Allows time controlled loops.

Syntax
WaitPeriod( [<nWaitPeriod>] ;
          ) --> lPeriodNotPassed
Return

Returns .T. as long as the period of <nWaitPeriod> * 1/100 seconds has not passed since the initial call to the function.

Description

The function allows a loop to run a specified period of time.

With the initial call the wait period must be specified in 1/100 seconds. After initialization of the internal timer the function must be called without an argument and can be used in a conditional expression: 

WaitPeriod(100) 
DO WHILE WaitPeriod() 
   // code to run for 1 second 
ENDDO
