Decrementing an integer

Hi there.

Is there a way to increment an integer value, or a string? (for example: to add 2 to 5 (result: 7 (doh))

set var 5
set varr [incr $var -2] doesn't work

greejtz, Zygo.

To add 2 to a variable, you would either use:

Code: Select all

set variable 5
incr variable 2

Or:

Code: Select all

set variable 5
set variable [expr $variable + 2]
