SYNOPSISlsort ?switches? list
_________________________________________________________________DESCRIPTION
This command sorts the elements of list, returning a new
list in sorted order. By default ASCII sorting is used
with the result returned in increasing order. However,
any of the following switches may be specified before list
to control the sorting process (unique abbreviations are
accepted):
-ascii Use string comparison with ASCII col-
lation order. This is the default.
-integer Convert list elements to integers and
use integer comparison.
-real Convert list elements to floating-
point values and use floating compari-
son.
-command command Use command as a comparison command.
To compare two elements, evaluate a
Tcl script consisting of command with
the two elements appended as addi-
tional arguments. The script should
return an integer less than, equal to,
or greater than zero if the first ele-
ment is to be considered less than,
equal to, or greater than the second,
respectively.
-increasing Sort the list in increasing order
(``smallest'' items first). This is
the default.
-decreasing Sort the list in decreasing order
(``largest'' items first).
