Do While reqReader.EndOfStream = False
temp = reqReader.ReadLine()
aryTemp = temp.Split(":")

If testNew < aryTemp(0) Then
testNew = aryTemp(0)

reqNum = aryTemp(0)
srcBldg = aryTemp(1)
dstBldg = aryTemp(2)
usrFneNum = aryTemp(3)

'call validate()

Public Declare Sub Sleep Lib "kernel32" Alias "Sleep" (ByVal dwMilliseconds As Long)
do while 1>0 'endless loop
'do something
sleep(1000) 'waits 1000 ms = 1 s
