The Form Specification File

A form containing a progress bar is defined in the form specification file reportprog.per.

Form reportprog.per:

01 LAYOUT (TEXT="Report")
02  GRID
03  {
04
05        [f001                  ]
06
07        [ib                    ]
08
09
10  }
11  END
12 END
13
14 ATTRIBUTES
15 PROGRESSBAR f001 = formonly.rptbar, VALUEMIN=1,VALUEMAX=10;
16 BUTTON ib: interrupt, TEXT="Stop";
17 END

Note:

Line 05 contains the form field for the PROGRESSBAR.
Line 07 contains the form field for the interrupt action view.
Line 15 defines the PROGRESSBAR as FORMONLY since its type is not derived from a database column. The values range from 1 to 10. The maximum value for the PROGRESSBAR was chosen arbitrarily, and was set rather low since there are not many rows in the customer database table.
Line 16 defines the button ib as an interrupt action view with TEXT of "Stop".
