Declaration:

handleRclKey
(BOOL
ReplaceCRs
)
Category(ies):
Operating System, Keyboard, Variables
Description:
Manages the dialog box which appears when
2
£
is pressed.
A pop-up dialog box is displayed requesting the name of a variable. The
contents of the variable are converted to text and pasted to the current
application.
Inputs:
ReplaceCRs
— If TRUE, carriage returns are converted to colons after
the contents of the variable have been converted to
text. The variable itself is not changed.
If FALSE, carriage returns remain unchanged.
Outputs:
None
Assumptions:
The current application receives a CM_PASTE_HANDLE command. It is
the responsibility of the application to make sure the handle contents are
pasted to a text field or to call the default event handler for this message if
the app has no active text field.
Nothing is pasted if the user pressed
N
to cancel the
2
£
dialog.
Side Effects:
May cause heap compression. May throw errors.
