Numeric check

This option specifies what type of numeric checking should be done by the emulator when the host defines an unprotected field as being numeric. There are four possible values that can be set:

None
No numeric checking is done. This is equivalent to a Typewriter keyboard selection in some emulators.

Strict
Numeric checking is enforced, and only numeric digits, decimal point, comma and minus sign may be entered in the unprotected field.

Emulator
Same as above but also allows plus sign (this is the numeric checking that is implemented in several other emulators).

Relaxed
Allows all of the above, also uppercase letters and shifted numerics (for example "!" and "#"). This is equivalent to a Data Entry keyboard selection in some other emulators.

The default setting is None, i.e. numeric checking is not performed.

`None`	No numeric checking is done. This is equivalent to a Typewriter keyboard selection in some emulators.
`Strict`	Numeric checking is enforced, and only numeric digits, decimal point, comma and minus sign may be entered in the unprotected field.
`Emulator`	Same as above but also allows plus sign (this is the numeric checking that is implemented in several other emulators).
`Relaxed`	Allows all of the above, also uppercase letters and shifted numerics (for example "!" and "#"). This is equivalent to a Data Entry keyboard selection in some other emulators.
