input Input is the information gathered during data collection or the action of
gathering the information.
Input node An Input node designates what type of portable input is acceptable
and where the input is stored.
jointed Link A jointed Link is a Link that has two or more segments intersecting at
an angle/
Link 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.
Math node A Math node performs mathematical operations on given data.
Menu node A Menu node presents a menu of options on the portable’s screen
and specifies what actions will occur when the user presses function
keys associated with those options.
Modify node A Modify node changes given data.
node 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.
Operation Nodes Menu , Display , Input , Output , Verify , Copy , Modify , Math , and
Call nodes are types of Operation Nodes. Refer to Function Nodes for
Frames and Subroutines .
object An object is the generic term for a frame, node, or Link.
Output node An Output node is used to transfer data to a portable’s display or to
the host computer.
portable file 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 source
file 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.
record A record is a set of related data fields stored as a single line in a file.
