APPLICATIONS MAKER - HELP FOR STRING TYPES
In programming languages a STRING is defined as an array of
characters. STRINGS can hold words or sentences. The data you are
reading now is of type STRING.
The STRING ITEMS can be of six types: ENTRY, READ, AUTO-FILL, MENU,
KEY and STATIC.
ENTRY: With the ENTRY type your user enters the string.
READ: With the READ type the string is read into item from a
relational file. Before data can be read in the target record must
be found in the file on the basis of KEYS, covered later in this
screen.
AUTO-FILL: With the AUTO-FILL type the string is filled with an
entry made during setup, the computer time or the record number of
the currently loaded record in one of your files.
MENU: With the MENU type the program opens a window on the input
screen and offers the user a choice of multiple, pre-defined entries.
The entry displayed/chosen need not be the same as the value placed
into the item.
Menu definition files are originated with a word processor operating
in the pure ascii mode. These files are named at the time of
initialization.
Each possible choice on the menu, of which there can be up to one
hundred, should have TWO lines dedicated to it in the menu file. The
first line can have up to 60 characters, and holds the text proffered
to the user. The second line contains the string to be recorded in
the item, and may be the size of the target item.
The menu definition files MUST be recorded in the datafile of the
MENU ITEM. If your menu item is recorded into file three then the
program will attempt to open the file in the directory holding file
three. If your menu file is not associated with a file then the
program will look for it in the directory of the first file loaded.
KEY: String is used as basis of identification of a record in a
relational file. Help for KEYS is available by selecting the KEY
type then pressing H again.
STATIC: With the STATIC type the item is left alone. It is usually
the target of a string formula.
