15–12 RSView32 User’s Guide
You can define symbols in a macro or on the command line. However,
symbols are mainly an operational convenience when using the system
from the command line.
To define a symbol:
On the command line or in a macro, type:
Define <symbol> <string>
<symbol> the abbreviated command, without spaces
<string> an existing command with or without parameters. It
can contain spaces and other symbols.
Example: The Define command
Define Show Display Overview
In this example, the command Display Overview is replaced with the
word Show.
Important guidelines
When creating symbols, keep the following in mind:
RSView32 does not check for security access on symbol names.
Therefore, be sure to put security on the underlying RSView32
command. For more information, see Chapter 10, Adding security.
A symbol and a macro should not have the same name. If they do,
the symbol runs instead of the macro.
The order of precedence is: symbol, command, macro.
