SECTION 3 -- TAE COMMMAND LANGUAGE

This section describes the TAE Command Language (TCL). TCL has the following general capabilities:

3.1 OVERVIEW OF TCL PROCESSING

The basic unit of execution in TCL is the command string. A TCL command string may be a TCL intrinsic command or a proc invocation. The TCL intrinsic commands are listed in Table 3-1.

TAE obtains a command string from a command line source and determines whether the string is a TCL intrinsic command or a proc invocation. If the string is a proc invocation, TAE locates the PDF and executes the proc.

Procedures may contain invocations of other procedures. Commands received from the interactive user are said to be executing on the "primary level." A procedure invoked from the primary level executes at "level 1." A procedure executing on level 1 may invoke another procedure, which executes at level 2, and so on.

Details on TCL commands commonly used at the interactive level, and details on proc invocation are supplied in the "TAE Command Language (TCL) User's Manual." Details on TCL commands primarily used in procedures are described in the following sections.
