;     QikPad is a functional text editor written around a normal edit
;     control. It has a size limit of 32k which is dictated by the
;     operating system for a control of this type. It has normal file
;     save confirmation, will load files from the command line and has
;     a working toolbar. It will open long file name files in the normal
;     manner.
