Glossary
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 | Program flow charts created with PPG are stored in DOS data files |
file | 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. |
