Hi Miyako, Thank you for clarifying this.
My reason for asking is this : We are using 4D for OCI to interact with an Oracle database In our tables we have text columns (VARCHAR2) with length 255, text columns with length 4000 and CLOBs I was hoping that I could use the variable type property to determine if I am dealing with a 255 or 4000 variable for example so I can prevent the user from typing more characters than possible for the corresponding column I know I can solve this with object naming for example "my_text_field", "my_string_field" but I was thinking of another way When I know the "subtype", I can then handle typing in the "On before keystroke" Off course setting a max length field as property for an object would be the ideal world.
