Macro Command Examples

The following sections give a few examples of how Scheme commands can be used in TracePro. There are two ways to use Scheme commands:

1.As part of a Scheme program stored in a text file (with default extension

*.scm), or

2.entered at the command line at the bottom of the message/macro window.

All the commands in the following sections can be entered at the command line to illustrate their effect.

Running a Macro Command from the Command Line

To issue a macro command, open the Macro Window that lets you run commands from the command line: select from the Macros menu, Macros|Output.

To enter a command, type into the one-line text box at the bottom of the Message/ Macro window, Figure 8.1. To run a command, select the Execute button.

Note: All commands must be enclosed in parentheses.

The Message/Macro window can be re-sized by dragging a corner or edge with the mouse. It can be maximized or minimized using standard Windows buttons and menus.
