' def fnCTICKS.def -- returns the number of clock ticks since midnight
'
' Allows the caller to `mark' the time, with an optional offset
' ahead in time. Useful in timing routines
'
' USAGE:
' HUN.SCNDS = 100
' MARK! = FNCTICKS (HUN.SCNDS) ' # of clock ticks that will
' 'have occurred since midnite (in 1 sec. from now)
'
'input: HUN.SCNDS = hundredths of seconds from now
'output: TIME.MARK! = time marker calculated (clock ticks since midnight)
