Do the Following:

Consider the following FORTRAN code

SUBROUTINE SORT $($A$,$N$)$

INTEGER $A(100),N,$I,$J,$SAVE,$M$

C ROUTINE SORTS ARRAY A INTO DESCENDING ORDER

IF $($N$.$LT$\mathrm{.}2)$ GO TO $40$

DO $30I=2,N$

$M=I-1$

DO $20J=1,M$

IF $($A$($I$).$GT$.$A$($J$))$ GO TO $10$

GO TO $20$

$10$SAVE$=A(I)$

$A(I)=A(J)$

$A(J)=$SAVE

$20$ CONTINUE

$30$ CONTINUE

$40$ RETURN

END

Where it requires about $11\mathrm{.}6$ mental size to program such code$($potential volume$).$

You are requested to do the following:

A$.$ Calculate the code length.

B$.$ Calculate the code Vocabulary.

C$.$ Calculate the code Value.

D$.$ Calculate the code difficulty

E$.$ Calculate program level

F$.$ Estimate the required time for a programmer to code it$.$
