{FINANCE}/{Str}
• Note that the EQUATION and FINANCE items appear for function keys (3 and 4) only
when you access the variable data menu from the Run-Matrix or Program mode.
• The variable data menu does not appear if you press J while binary, octal, decimal, or
hexadecimal is set as the default number system.
• For details about the commands included on the variable data (VARS) menu, see the “J
key” item in the “Program Mode Command List” (page 8-52).

The dot value indicates the display range (Xmax value – Xmin value) divided by the
screen dot pitch. The dot value is normally calculated automatically from the
minimum and maximum values. Changing the dot value causes the maximum to be
calculated automatically.
