The start and end graphic modes are used whenever PRO/5 will print one of the graphics sequences. Problems similar to those in attribute setting exists.

If it is possible to print the box characters without a special mode, the GS and GE capabilities should be left blank. If none of the strings are loaded, PRO/5 will default to "*" for the corners, "|" for the vertical lines, and "-" for the horizontal lines.

If "GG" is specified, this is the same as not having any special graphics characters. PRO/5 cannot use attributes that require display positions.
