-C     Substring range checking test program, to check behavior with respect
-C     to X3J3/90.4 paragraph 5.7.1.
-C
-C     Patches relax substring checking for subscript expressions in order to
-C     simplify coding (elimination of length checks for strings passed as
-C     parameters) and to avoid contradictory behavior of subscripted substring
-C     expressions with respect to unsubscripted string expressions.
-C
-C     Key part of 5.7.1 interpretation comes down to statement that in the
-C     substring expression,
-C        v ( e1 : e2 )
-C     1 <= e1 <= e2 <= len to be valid, yet the expression
-C        v ( : )
-C     is equivalent to
-C        v(1:len(v))
-C
-C     meaning that any statement that reads
-C        str = v // 'tail'
-C     (where v is a string passed as a parameter) would require coding as
-C        if (len(v) .gt. 0) then
-C           str = v // 'tail'
-C        else
-C           str = 'tail'
-C        endif
-C     to comply with the standard specification.  Under the stricter
-C     interpretation, functions strcat and strlat would be incorrect as
-C     written for null values of str1 and/or str2.
-C
-C     This code compiles and runs without error on
-C       SunOS 4.1.3 f77 (-C option)
-C       SUNWspro SparcCompiler 4.2 f77 (-C option)
-C       (and with proposed patches, gcc-2.9.2 -fbounds-check except for test 6,
-C        which is a genuine, deliberate error - comment out to make further
-C        tests)
