Input is the information gathered during data collection or the action of
gathering the information.
An
node designates what type of portable input is acceptable

and where the input is stored.
A jointed

an angle/
A Link connects two frames or nodes with an arrow directing the pro-
gram to the next step. A Link pointing to a frame or node shows how it
is accessed. A Link pointing away from a frame or node shows where
the program goes next.
A
node performs mathematical operations on given data.

A
node presents a menu of options on the portable's screen

A node is a shape in a program flow chart that represents one step in
the program. There are different types of nodes for each kind of action
that can be performed by the program. Detailed instructions for the
action are specified by settings in a dialog box associated with the
node. A connected set of nodes makes up one frame or subroutine. of
a program flow chart.

An object is the generic term for a frame, node, or Link.
An
node is used to transfer data to a portable's display or to
Output
the host computer.
Data that has been either input via a portable's scanner or data keys
or downloaded from a PC file through the serial port is saved in a por-
table file. Each entry in the portable file is called a record, and the
records in each portable file are numbered, starting with 1 for the first
record.
Program flow charts created with PPG are stored in DOS data files
called program source files. A program source file must be compiled
(using PPGComp) before it can be loaded into a portable.
A record is a set of related data fields stored as a single line in a file.
