wvar-name

contains the name of the FRAME or PROGRAM entry control or field on which the cursor is currently positioned.

Type: Character

Details

The CURFLD function returns the name of the field FRAME or PROGRAM entry control on which the cursor is located. If the cursor is not positioned on a window variable, a null string is returned. CURFLD is usually used in conjunction with a CONTROL statement that includes the ENTER, ALWAYS, or ALLCMDS option. You can use CONTROL LABEL to achieve the same result more efficiently. FRAME or PROGRAM entries can also use the _getCurrentName method.

Example

Use CURFLD to control the behavior of an SCL entry application:

INIT:
   control enter;
return;

MAIN:
   select( curfld() );
      when('PHONE') call display('phone.help');
      when('EMPLOYEE') call display
                          ('employee.scl');
      otherwise;
   end;
return;

This example can be implemented without CURFLD if the program contains a program block that is labeled with the name of the window variable. If the program is in a SCL entry, then the window variables must be of type PUSHBTNC or PUSHBTNN, and the INIT section must contain CONTROL LABEL.

INIT:
   controllable;
   return;
PHONE:
   call display('phone.help');
return;
EMPLOYEE:
   call display('employee.scl');
return;
