If using PascalP version 3.1.9 up, READ(f, string), LENGTH(string)
standard procedures may be used in place of READSTRING and LENGTH
in this package.  Similarly you may use READLN(f, string).  These
standard procedures also all use the default input file when the
file specification is omitted.

The new READ function is slightly different from READSTRING in that
it stops reading when the string is full, or on eoln, whichever
comes first.  This allows a long line to be read into multiple
strings.  If you want to flush the line remnant use READLN.  In 
addition you do not supply the maxstring parameter.

Simply delete the READSTRING and LENGTH procedures from STRINGS.INC
file if you have version 3.1.9 up.  Make suitable modifications in
the TEST program.  Note that 3.1.9 will also accept this package
unchanged.

3.1.9 also provides

   STRINGCP(VAR s1, s2 : string) : integer;

                    function, which compares strings.  It returns
-1, 0, +1 for s1 >, =, < s2., and thus makes the STRINGCLEAN
function in this package unnecessary. 

I am not altering this package so that it will continue to function
on earlier versions, and on Standard Pascal systems.  I have however
crunched the members of this library.

The PascalP 3.1.9 manual gives a further explanation of the added 
string functions.
