position the cursor to a blank line to which you wish the fields moved<br />press PF17 (or, PF3 to abandon move operation)<br />NOTE:<br />**<br />You can also move a line by typing the target line number into the pop-up window, rather than by pointing with the (cont.)<br />cursor. This method also allows you to move a line from one Mask to another by typing a target Mask number, as well. If (cont.)<br />you type into either the Mask number or the Row number in the pop-up window, the line will be moved immediately and you (cont.)<br />will not be required to point with the cursor and press PF17.<br />## <br />Deleting a Blank Line<br />You can delete a blank line (one on which there are no detail fields) from your mask using PF13 (Shift-F3, on a PC) (cont.)<br />key. Actually, deleting a blank line consists of moving all screen fields below that line up one line on the mask. You (cont.)<br />cannot delete a line which has fields on it. If you wish to do so you must first erase the line (using PF5), then (cont.)<br />delete it.<br />To delete a blank a line:<br />position the cursor onto the desired line to be erased<br />**(anywhere in the line)<br />press PF13<br />(message in SCOMPL tells you that the line was deleted, or gives an error message)<br />## <br />Inserting a Blank Line<br />You can insert a blank line into your mask using the PF14 (Shift-F4, on a PC) key. Actually, inserting a blank line (cont.)<br />consists of moving all screen fields which are below that line down one line on the mask.<br />To insert a blank a line:<br />position the cursor onto the line after which* you would like a line inserted<br />(anywhere in the line, whether on a field or not)<br />press PF14<br />(message in SCOMPL tells you that the line was inserted, or gives an error message)<br />## <br />Adding a New Field<br />Adding new fields to a mask is done by drawing them directly onto the image displayed. MSKDEF scans the screen image (cont.)<br />looking for new fields you have drawn. When it finds one (or more) it automatically adds a detail field definition (cont.)<br />record (for each one) to the MAGEC repository. Then you can modify it just as you can any other field on the (cont.)<br />screen.<br />There are two basic types of screen fields: variables and constants, as discussed earlier. Drawing new constants is the simpler task, so we will discuss it first.<br />New constants can be drawn by simply typing their value (contents) onto the screen in the exact position where you want the new field(s) to be, preceeding each new field with a less-than symbol ( *
