This menu gives a list of the variables in the data object for filling
in between the ( and ) in the object name contained in the selection
region of the main menu.


You can fill in strings by

  1) typing/editing
  2) Selecting a string from the list by double--clicking the left
button and highlighting the item with the mouse, moving to the selection
box and clicking the second mouse button.

You restrict the var1ables by:

  1) putting conditions on them (e.g., press<500). For these you use
the variable names and the <,=,>,<=,<>,>= and the &,|[or], and ![not]
conditions with parentheses as necessary.

  2) choosing only a subset of variables to return (e.g.,
station,press,o2). For that kind of restriction, you simply select and
move over the variable names, using the "," button to add the comma.

A final string might look like

#pco2(station>29&station<35,press,pco2)
