\fBarray startsearch\fR. Returns an empty string.
.TP
\fBarray exists \fIarrayName\fR
Returns 1 if \fIarrayName\fR is an array variable, 0 if there
is no variable by that name or if it is a scalar variable.
.TP
\fBarray for {\fIkeyVariable ?valueVariable?\fB} \fIarrayName body\fR
The first argument is a one or two element list of variable names for the
key and value of each entry in the array. The second argument is the
array name to iterate over. The third argument is the body to execute
for each key and value returned.
The ordering of the returned keys is undefined.
.TP
\fBarray get \fIarrayName\fR ?\fIpattern\fR?
Returns a list containing pairs of elements. The first
element in each pair is the name of an element in \fIarrayName\fR
and the second element of each pair is the value of the
array element. The order of the pairs is undefined.
If \fIpattern\fR is not specified, then all of the elements of the

The ordering of the returned keys is undefined.
If an array element is deleted or a new array element is inserted during
the \fIarray for\fP process, the command will terminate with an error.
