- % money_funcs
-
- Money editing functions.
- These functions use a long and put a decimal point at position 2.
- The value returned is in cents. Divide by 100 to get a dollar amount.
-
- Normally this functions saves enough space at the left of the field
- to display a minus sign. (toggled with the '-' key).
- If you wish to disable this feature undefine the symbol MINUS and
- recompile this file.

- 9/24/88 jmd clears after first key pressed
- 10/09/88 jmd added SED_ABORT support
- 10/14/88 jdc added var_size element to field_funcs_struct
-
- 6/07/89 jmd added test for mouse code (later removed)
-
- 1/31/90 jmd don't reset baton on MOU_CLICK
- 3/14/90 jmd moved formatting before validation
- 3/28/90 jmd ansi-fied
