Abstract

Variable transparency allows the user to reference both program/application variables and variables pertaining to the environment outside the application's domain without resorting to alternate commands or other syntactic schemes. XDE is an advanced software development environment targeted for the IBM RT PC* running IBM's proprietary UNIX** operating system, AIX***. This environment contains two types of variables: those which are specific to the environment itself, similar to shell variables, and those which are internal to the developing application. The environment variables, as well as the application's internal variables, may be referenced in some way to either obtain and print its value or to assign a new value. Variables which are not part of the application are environment variables.
