Calculate variable Y for two different call sequences: (15) Dynamic scope STOCK calls MU3 which calls MU1 STOCK calls MU2 which calls MU1 (15) Static scope STOCK calls MU3 which calls MUI STOCK calls MU2 which calls MUI 1. Consider the following program: PROCEDURE STOCK IS Y: Float: -8.3; PROCEDURE MUT IS BEGIN = OF MUI Y: Y-3.1; END; --OF MUI PROCEDURE MU2 IS Y: Float:-9.8; BEGIN --OF MU2 END; --OF MU2 PROCEDURE MUS BEGIN OF MU3 END; --OF MU3 BEGIN --OF STOCK END; --OF STOCK
