Operations that work on strings, whether constructing, modifying
or examining them.

=item B<chopn>(inout STR, in INT)

Remove n characters specified by integer $2 from the tail of string $1.
If $2 is negative, cut the string after -$2 characters.

Remove n characters specified by integer $3 from the tail of string $2,
and returns the characters not chopped in string $1.
If $3 is negative, cut the string after -$3 characters.

=item B<concat>(in PMC, in STR)

=item B<concat>(in PMC, in PMC)

Modify string $1 in place, appending string $2.
The C<PMC> versions are MMD operations.

=item B<concat>(out STR, in STR, in STR)

=item B<concat>(in PMC, in PMC, in STR)

=item B<concat>(in PMC, in PMC, in PMC)

=item B<n_concat>(out PMC, in PMC, in STR)

=item B<n_concat>(out PMC, in PMC, in PMC)

Append strings $3 to string $2 and place the result into string $1.
The C<PMC> versions are MMD operations.
The C<n_> variants create a new PMC $1 to store the result.
See F<src/ops/math.ops> for the general C<infix> and C<n_infix> syntax.
