SAVE FIELD MENU
SAVE FIELD MENU
A save field is a global field whose value can be used anywhere in the forms file where field
references are allowed. Save fields are not part of a particular form like other fields, but
are "global" to all forms. Like other fields, they always contain data in external, character
form. The save fields can be used by most processing statements, but are particularly
useful for passing data between fields on different forms. Refer to the SET command in
Section 4. A maximum of 20 save fields can be defined for any forms file.
Save fields are specified on the Save Field Menu, which is displayed when requested on the
Main Menu. Any defined save fields are stored at the beginning of the forms file just after
the global specifications. (Refer to "Forms File" earlier in this section for the order of
specifications in the forms file.) The Save Field Menu is illustrated in Figure 3-24.
Figure 3-24. Save Field Menu
A save field name appears exactly the same as a field name. To help distinguish the global
save fields from local fields, you may want to establish a naming convention. For example,
if all save field names (and no local field names) start with the letter SF, then any field
name starting with SF is immediately recognizable as a save field.
Up to 20 save fields can be defined in one forms file. The Save Field Menu is usually
requested through the Main Menu. To add a save field, press MAIN/RESUME to request the
Main Menu and then type S in the selection box and press
ENTER. A blank Save Field
Menu is then displayed. You can also display a blank Save Field Menu by pressing PREV
from the first Form Menu.
To delete a save field, you also request the Main Menu and then enter D in the selection box
