tcl.:swx

leftover from early Pick as a utility to change a file-defining item from a 'd' in attribute one to 'dx' or 'dx'.

Setting the file-defining item (d-pointer) to dx or dy, prevents the file from being saved on a 'save-type' (account-save, file-save, etc.) backup.

Advanced Pick uses the 'ud' macro for updating the 'd/code' attribute. (The line editor 'ed' can only be used on 'd-pointers' when issued with the 'd' option). ':swx' is provided for backward compatibility only and should NOT be used in Advanced Pick.
