|-

| '''{{key press|&}} || Ampersand

| An ampersand {{kbd|&}} at the end of a line of TACL commands or function calls signals that the line continues on the next physical line. This continuation applies to executable statements and comments, with two exceptions:

* TACL does not interpret data transmitted by a process or file opened using #REQUESTER or #SERVER; any special characters are treated as text. If you receive a line that contains an ampersand, TACL does not view the ampersand as a continuation character.

*You cannot use the continuation character with a TACL directive (a line beginning with a question mark).
