fgl_dialog_setcurrline()
The fgl_dialog_setcurrline() function displays a specified row of the program array at a specified line of the screen array.
The fgl_dialog_setcurrline function takes two comma-separated arguments (screen_line, prog line), where screen line is the screen line number in the array, and prog line is the row number in the program array.
The code sample below creates a display using two ON KEY options. When you press the F4 key, the 4th row of the program record is displayed.
