XFBar-macro
Shows the control panel for X-Function use when the input argument is not "C". When the control panel is open, you can choose the X-Function you want.
Def XFBar { if("%1"!="C") page -sps "c[PageXFBar]{210}c";else page -sps; }
When an object (workbook, graph, or matrix) is active, the first script shows the X-Function control panel on the left side of the chosen page, and then the second script closes the X-Function control panel.
