; when archive_ps ne 0, we add the name and the date at the bottom left corner

; If the postscript is called idl.ps we change its name to number.ps

;
; @keyword INFOWIDGET {type=long integer}
; id of the information widget (created by <pro>openps</pro>)
; that we have to destroy at the end of closeps (when the postscript is done).
