Parameter Info is a feature that helps the user write code by displaying information about intrinsic procedures as the user is typing. Parameter Info is currently implemented for all Fortran 95 intrinsic procedures, and Lahey extensions supported by LGF.
As a procedure invocation is typed, the open parenthesis character triggers the Parameter Info tooltip for the first argument:
As typing continues, each succeeding comma character that is typed will trigger a tooltip for the next parameter:
When a close parenthesis character is typed, the tooltip window is dismissed. The tooltip window is also dismissed whenever the cursor is moved outside of the area of the argument list.
The Parameter Info tooltip can also be opened by placing the cursor within the argument list for an instrinsic function, and clicking on the "Display Parameter Info" tool button. The tool button appears on the "Text Editor" toolbar.
