the /F indicates the vars will be taken from a file which we name in (results.txt).

'for' by default uses a space to delimit items in each line. tokens=3 means we'll be using the third item. (it actually places them in an array).

if we had said "tokens=5" %X

%X would equal "time=70ms"

enter "for /?" at a command prompt for an in depth help file. if youd rather ask, ask away! BTW this does not apply to 9x systems only nt based. the for command in 9x is very weak.
