.SH DESCRIPTION
 
10
This command kills variables which are not protected.
 
11
It removes the named variables from the environment.
 
12
By itself \fVclear\fR kills all the variables except the variables
 
13
protected by \fVpredef\fR. Thus the two commands \fVpredef(0)\fR and \fVclear\fR
 
14
remove all the variables. 
 
15
.LP
 
16
Normally, protected variables are standard libraries and variables with
 
17
the percent prefix.
 
18
.LP
 
19
Note the particular syntax \fVclear a\fR and not \fVclear(a)\fR. Note also
 
20
that \fVa=[]\fR does not kill \fVa\fR but sets \fVa\fR to an empty matrix.
