DOCERR: Code in Manual Incorrect: COMMON and Equivalance (77574)
The information in this article applies to:
- Microsoft FORTRAN Compiler for MS-DOS 5.1
- Microsoft FORTRAN compiler for OS/2 5.1
This article was previously published under Q77574 SUMMARY
The sample program on page 132 of Advanced Topics version 5.0, page 105
Advanced Topics version 5.1 is incorrect. The code is as follows:
integer a(10,20), b(20,30)
common /cba/a, /cbb/b
equivalence (a(10,20),b(1,1))
end
The ANSI standard states (p. 165 of REFERENCE manual):
An EQUIVALENCE statement cannot share memory between two different
common blocks or between elements of the same common block.
Since the program attempts to equivalence items in two different COMMON
blocks, the compiler generates the error:
error F2318: A, B : EQUIVALENCE : in different common blocks
