I can't find good tutorial about syntax of / %.

In expect script I am trying to do something like this:

set size [file size $tp_receive_to_path]
# Now check if it return 0
if { $size mod 72 != 0 } {
# receive file! Retry
send -s -- "get $tp_receive_to_tmppath
$tp_receive_to_path\r"
}

Is syntax of if and mod correct ?

Say... Don't you see a nice and self-explanatory error message like

invalid bareword "mod"
in expression " $size mod 72 != 0 ";
should be "$mod" or "{mod}" or "mod(...)" or ...

Then, go to [expr] manpage and look for operator "%".
I'd also put in more explicit grouping: {($size % 72)!=0}
