If you want to increase or decrease the number of lines of text in the boxes of a chart, or to alter the labeling of these lines in the entry forms, or to change the default properties of boxes or of individual text lines, then you will need to use the DEFINE-FORM command in the top menu. When you invoke this command, a new menu is displayed. Using this menu you can change the number of lines per box and you can set the default properties. Also, a special entry form is displayed. The text fields in this form contain the strings used to label the lines in the entry forms for the individual boxes. For example, the default chart created when ORCHIS is first loaded has three lines per box, and these lines are labeled "Name", "Title" and "Comments" respectively. Invoking the DEFINE-FORM command will display the entry form illustrated in <[FIG03]>.

Use the ADD-LINE command to place additional text lines in the boxes of the current chart. When you invoke this command, a new field is added to the special entry form in the chart window. You are asked to select which field in this form is to be the new field. In this way, the new line can be added above, below, or in the middle of the existing text lines. The new field is initially blank. Select the new field with the cursor or by using the TAB key if you want to supply a label for that field in the entry forms for this chart. Note that all boxes in a given chart have the same number of text lines in their entry forms. When you use the ADD-LINE command, you are adding a new line to every box in the chart. Initially, this line will be blank. If you want to show fewer lines in some boxes than in others, you can use the HIDDEN-LINE property, which can be turned on and off for individual lines independently in the various boxes of the chart.

Use the REMOVE-LINE command to delete text lines in the boxes of the current chart. When you invoke this command, you are prompted to select the field that you want to delete. Position the cursor in the chosen field and press the left mouse button or the keyboard ENTER key. The selected line will be deleted from every box in the chart. Once a line is removed, the deleted information cannot be recovered; therefore, ORCHIS requires a verification for each line removed by this command.

Use the DEFAULTS command to change the default values for the various properties of boxes and text lines. When you set a property value here, it will apply everywhere in the chart, except for those boxes in which it is overridden by an explicitly set property value. When you invoke the DEFAULTS command, a property sheet is displayed containing the default values for all box properties. You can then use the NEXT-LINE <[3.1]> and FORMER-LINE <[3.2]> commands (or the PGDN and PGUP keys) to display the default properties for the various text lines. (You can also bypass the DEFAULTS command and display any of these default property sheets directly by clicking on the appropriate [P]-button in the entry form for the DEFINE-FORM menu). Default sheets are manipulated in the same way as ordinary property sheets. For complete information on using property sheets see Chapter <[3]>.
