14.1.3 Run the program Save the file, name the code unit as CUST.PAS, name the project name CUSTPRJ.DPR, and then press F9 to compile and run the program. After the program is executed, we can use the scroll bar or the keyboard to move the key between the fields and records. However, the data in the table cannot be modified because the Datasouc1.autoedit1 property has been set to false. The three parts in the Cust program have their own special uses, and the related properties of the three com
