Abstract
A masked edit program object for use in a graphical program-development environment is configured to have an Allow_Literal_Entry property that may be set as true or false, and an Insert_Zeros property that may also be set to true or false. If the Allow_Literal_Entry property is set to true, then at run-time when the program user enters a literal, the program object does not reject the literal as invalid entry, but rather searches the input mask for the entered literal and moves the cursor to the location in the input mask that is adjacent to the located literal. If the Insert_Zeros property is set to true, the program object will enter leading or trailing zeros in empty entries of the input mask that have been configured with specially-defined symbols for accepting leading or trailing zeros.
