Reading the Data into Variables

PV-WAVE Foundation > VDA Tools > WzPreview > Reading the Data into Variables

If you click on the Read button in the controls area, WzPreview uses whatever region definitions are currently in effect, and actually reads the file.

It is only at this time that the specified variables are actually created—one variable for each defined field.

note	If a variable already exists on the $MAIN$ program level, you will be notified and given a chance to either overwrite or rename the variable. If you rename the variable, reselect Read to read the data.
