subroutine ftc2s(in,cval,status)
C convert an input quoted string to an unquoted string
C
C The first character of the input string must be a quote character (')
C and at least one additional quote character must also be present in the
C input string. This routine then simply outputs all the characters
C between the first and last quote characters in the input string.
C
C in c input quoted string
C cval c output unquoted string
C status i output error status (0=ok, 1=first quote missing,
C 2=second quote character missing.
