If this command is not used with the FORTRAN-like languages, the ‘//’ construction will be interpreted as concatenation rather than as the beginning of a short comment.
Concatenation can be signified with FWEB’s token‘\/’, so no penalty is incurred for using ‘-/’.
One way of invoking this option is with the global language command, such as ‘@n/’. Another is to put the command into the initialization file .fweb.
