Zeroing data

ZE -- ZEro data set

Replaces all data points with zeroes and the previous data are lost. A dialog box requests confirmation before executing.

BZ -- Baseline Zero

Zeros the region within the Zoom frequency limits without changing the rest of the data. Applies to both the reals and imaginaries. The Zoom subcommand ^Z (Control-Z) does the same thing.

ZR -- Zero Reals

Replaces the real half of the data by zeroes. Useful for some types of 2D processing.

ZI -- Zero Imaginaries

Replaces the imaginary half of the data by zeroes. Useful for some 2D processing.

ZN -- Zero Negative points

This command zeros all negative data points of both the reals and imaginaries.

The Z subcommand of the View routine will zero all points in the displayed slice.  It does not ask for confirmation.
