Hello,

This used to be a valid expression:

fexpr~$s3\[$x1\[0\]\] = $x2\[0\];
$s3\[$x1\[0\]+22050\] = $x2\[0\]

since last update of the expr library, this gives
the following error:

expr: symbol cannot be a left value '$s3[$x1[0]] = $x2[0] \; $s3[$x1[0]+22050] = $x2[0]'
expr_perform: bad result type 0

Any idea how I should rexrite the expression ?

Cheers

yog
