set \fIenvironment-variable\fP=\fIvalue\fP
.SH DESCRIPTION
The kernel debugger contains an environment which contains a series
of name-value pairs.  Some environment variables are known to the
various kernel debugger commands and have specific meaning to the
command; such are enumerated on the respective reference material.

Arbitrary environment variables may be created and used with 
many commands (those which require an \fIaddress-expression\fP).

The
.B env
command is used to display the current environment.
.P
The
.B set
command is used to alter an existing environment variable or
establish a new environment variable.   
.SH LIMITATIONS
There is a compile-time limit of 33 environment variables.
.P
There is a compile-time limit of 512 bytes (\fBKDB_ENVBUFSIZE\fP)
of heap space available for new environment variables and for
environment variables changed from their compile-time values.
.SH ENVIRONMENT
These commands explicitly manipulate the environment.
.SH SMP CONSIDERATIONS
None.
.SH USER SETTINGS
You can include "set" commands in kdb/kdb_cmds (see kdb.mm) to define
your environment variables at kernel startup.
.SH EXAMPLES
