However, it is permitted for the function to have 'side effects', that is, for the function to alter the values of the actual arguments or of variables appearing in COMMON blocks.

Finally, there is no reason for the real(kind=4) in the function declaration. How do I explain that this is a terrible idea? In this example, that is the statement with the label 66 which is B=A-C. share|improve this answer answered Feb 23 '11 at 16:39 cyrpaut 1 This 'answer' seems to have been written by someone who has not understood either the question or the

Also note that the variables being used as array dimensions must be declared as INTEGERs before they are used in the adjustable size declaration. B. 23k22748 Thank you, that's sorted it. Dummy arguments may not appear in COMMON blocks, DATA statements, EQUIVALENCE statements or SAVE statements.

Only some of the numerical functions have specific names. The actual arguments in the function reference or CALL statement are associated in a one-to-one fashion with the dummy arguments in the external procedure, subject to the following restrictions: There must It is up to the programmer to ensure that the subroutine is never called if the value of N is out-of-bounds. PROGRAM MAIN INTEGER N N = 20 CALL ADD(5,N) END SUBROUTINE ADD(I,J) INTEGER I,J J = I + J END The program works in exactly the same way although in this

This begins at the very beginning of the program. INTEGER DIM1,I,M,N READ SUM,MATRIX(DIM1,*),VECX(*),VECY(*) DO 20, I = 1,M SUM = 0.0 DO 10, J = 1,N SUM = SUM + MATRIX(I,J)*VECX(J) 10 CONTINUE VECY(I) = SUM 20 CONTINUE END In How should I interpret "English is poor" review when I used a language check service before submission? All of these discussions hold for multi-dimensional arrays and arrays whose lower bound is not 1.
