Forum Post: Field Validation

$

Hello All, I am trying to resolve how to validate a text box (field) immediately after entry and to determine if the content is invalid. And if it is, to return the user to that field. I have tried  using the various "validation" properties ending only in the field trying to validate itself on every character to the field trying to validate itself constantly ect... What is the "new way" for the following "old way" of administering immediate field validation after the user has finished entering and before moving on to the next field. Here is the "old code" Sample procedural (linear) code        AF25.            ACCEPT TRN-ACCT-NO,      LINE 03, POSITION 25                                     PROMPT, ECHO, UPDATE                                     ON EXCEPTION ERR-CDE                                     GO TO ERR-EXCEPTION.            MOVE TRN-ACCT-NO TO CUS-ACCT-NO.            PERFORM VERIFY-CUST THRU VC-EXIT.            IF WS-REC-FND = "N"               MOVE "INVALID CUSTOMER !" TO ERR-MSG1               MOVE "Strike Any Key To Continue" TO ERR-MSG2               PERFORM DISP-ERR-WIN THRU DEW-EXIT               GO TO AF25.                       AF26.            ACCEPT.............(NEXT FIELD) I realize that I can validate all fields at once based on a given event... That being said,  it would be helpful to be able to handle it immediately as well. I am old ! So please be as explicit as possible in your example as I am still a newbie when it comes to event driven logic. Thanks in advance for your answers they are greatly appreciated. Allen
