+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)
