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)


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.
