You can use the Values tab in the Preview page screen controls to associate simulated runtime information with your records and fields. For records, you can specify the state of the option indicators when each record is written using the Indicators tab.
If the SLNO(*VAR) keyword was specified on the selected record, you can specify the line at which the record should start on the screen.
If the selected record has a WINDOW keyword with a *DFT parameter, that window will be positioned relative to the cursor at the time the record was written. Use the Cursor line and Cursor column fields to simulate the cursor position.
For each field within the records, you can simulate what the field would look like on the screen if the application gave it the value you specify in the Field value entry field. This value should not be formatted with currency symbols, commas or decimal points. For example, if you specified 123 for a field that has two decimal positions defined, it will be formatted as 1.23. To specify negative numbers, place the negative sign to the left of the number as in -123. The preview page will show your field with all the padding, truncation and editing with EDTCDE and EDTWRD keywords applied.
