hierarchical structure. The screen navigation structure that the Pathmaker product uses
when creating an application. In an application with a hierarchical structure, the
application's requesters are arranged in a fixed hierarchy, sometimes referred to as a
tree. Typically, this hierarchy has a main menu requester at the top level with sub-
menu requesters below leading to detail requesters (used for data entry or data
retrieval) at the lowest levels.
host language. Any programming language whose statements can be combined with
SQL statements in the same source program.
host program. A source program that contains statements written in both a host
language and SQL.
host variable. A variable declared in a host program and referred to by an SQL
statement embedded in the same source program. The Pathmaker product declares
host variables if host variable names have been specified in the Logical File Name
column of the Logical File Entries screen.
interprocess communication message. See IPC.
IPC (interprocess communication message). A unit of communication between requesters
and servers. The Pathmaker product generates interprocess communication messages
that have a standard header. IPC messages generated for Pathway Open Environment

logical screen. A logical screen defines the locations, lengths, and other attributes of
fields displayed on the end user's screen. The logical screen is equivalent to the Screen

macro. A unit of parameterized text that can be included in a generated source. A
macro can be pure text, equivalent to a copy library, or can use a macro language to
control the emitted text.
macro language. A language unique to the Pathmaker product used to create the
requester skeleton, the server skeletons, and the C service skeleton supplied with the
product. The language can be used by application developers to change the skeletons
supplied with the product or to create other application files such as macros. The
language consists of two types of statements: source lines and command lines.
menu (MENU) requester. A type of Pathmaker requester that allows data entry and
navigation to other requesters but does not support transmittal of data to a server.
message area. A reserved portion of the screen where messages and errors are
displayed to the end user. The message area on a Pathmaker default screen is below
