On the Company screen, Options tab, there is a setting that allows a user to set the Control Limits to be greater than the Spec Limits.
Typically the Control Limits (sometimes referred to as 'Process Limits') are within the Spec Limits
Example - In the screenshot below, the Range (in the green boxes) is +/- 1.000 and the Control Limits (in the red boxes) is set to 80% of spec limits or +/- 0.8000
With this option Not set on the company screen, the largest value that it will accept is "100.0 %". If you enter a larger amount it will adjust to 100.0 % after you tab off.
Note - The "Out of Control Limits" Font color is not applicable with this setting turned on.
