Output Curves

Output Curves

All operations that generate new curves must have a target curve defined. This must be one of the following:

#nnn a specific curve number nnn
# meaning "the lowest free curve"
% meaning "the highest free curve"

In all cases output will start at the relevant curve number, however defined, and will rise sequentially with no gaps. This can cause an existing curve to be overwritten, or the output curve number to exceed the limit of 999. Both conditions are checked for: a warning is given if either will occur should the operation go ahead, and an opportunity given to modify or abort the pending operation.

There is a further output option that is only valid for operations where the input is a curve group:

. meaning "overwrite the input curve(s)"


In this case the input curves are overwritten without warning. For example, this option might be used to integrate a set of curves, overwriting the original results with the integrated values.

Any curve number between 1 and 999 may be used as an input or output curve. It is not necessary to use curves sequentially; gaps are permitted in curve number usage. Therefore curves #1 and #10 can be used, for example, without having to use the intervening curves #2 to #9. Likewise, deleting a curve will no longer cause those above it to be renumbered downwards to fill the gap.
