Description:

The CHR library augments the limited character handling facilities
provided by the Fortran 77 standard. It offers a range of character
handling facilities: from formatting Fortran data types into text
strings and the reverse, to higher level functions such as wild card
matching, string sorting, paragraph reformatting and justification.
The library may be used simply for building text strings for
interactive applications or as a basis for more complex text
processing applications.
