Section 9. Datalogger Program Creation with CRBasic Editor
The Vertical Spacing tab is used to set up the rules for the CRBasic Editor’s
Rebuild Indentation function (Edit | Rebuild Indentation). You can control
whether blank lines are inserted before or after certain instructions, and how
the CRBasic Editor will process multiple blank lines in the program. If Do Not
Insert or Remove Any Blank Lines is selected, all other fields on this tab will
be disabled. If either of the other two line options is chosen, the remaining
fields will be available for the user to customize as desired.
