Character
Length
The following functions
are provided to return character string length (number of characters in
iword ignoring terminator character).
icharln(iword)Get
length by searching forward for first blank or null.
icharlnf(iword) Ignore
leading blanks then search for terminating blank or null.
icharlnb(iword) Search
backwards for first non-blank or non-null - uses FORTRAN function len
to give starting point (this is a risky assumption)
nulltoblank_lg(iword,length)
iword is the character string that
will be searched for null characters. All null characters will be
replaced by blanks.
length is the number of characters
in iword.
