GE v:	Search for and mark the first data point that is greater than or equal to v.

MARKVALUE GE 1 TO T0

DESCRIPTION

This command searches for the requested value in each data file and marks the time of the first occurance of that value. If a measurement time window has been defined (see MTW), only that portion of each data file is searched. Otherwise the entire file is searched. The results are written into the header in the requested time marker.

EXAMPLES

To search for the first data point whose value is at least 3.4 and to store the result in the header as T7:

SAC> MARKVALUE GE 3.4 TO T7

To later perform that same search in the measurement time window 10 seconds long beginning at T4:

SAC> MTW T4 0 10
SAC> MARKVALUE
