A PL/I program has variables U, V, X, Y, 2 which are declared as follows: DCL U BIT(4) W CHAR(5) Y CHAR(3) V FIXED (4,1), X FLOAT(4), Z FIXED(3); The Data Card for the same program contains the following information: U ='1101'B, V= 981.2: U='1101'B, V= 123 4, W='123•4',X= 1052E + 02. Y= 'PQR', Z=- 249; a) Show what will be entered into memory storage in the computer as a result of the statements: GET DATA; followed a little later in the program by the statement: GET DATA(Z,V,W,Y,U,X); b) In the same program at a later stage, the contents of the memory locations corresponding to U, V, W, X, Y and Z were changed to 0100 769.2 144.7 •0129E – 03 ВOG - 47 respectively. Show what will be printed out by the following statements: PUT DATA(U, Y): PUT SKIP DATA(X): PUT SKIP DATA(W,V.Z);

Question
A PLI program has variables U, V, w, X, Y, Z which are declared as follows: DCL U BIT(4) W CHAR(5) Y CHAR(3) V FIXED (4,1). X FLOAT(4), Z FIXED(3): The Data Card for the same program contains the following information: U ='1101'B, V = 981-2; U='1101'B, V= 123•4, W = '123•4', X= 1052E + 02, Y= 'PQR', Z=- 249; a) Show what will be entered into memory storage in the computer as a result of the statements: GET DATA; followed a little later in the program by the statement: GET DATA(Z,V,W,YU,X); b) In the same program at a later stage, the contents of the memory locations corresponding to U, V, W, X, Y and Z were changed to 0100 769.2 144.7 •0129E – 03 BOG - 47 respectively. Show what will be printed out by the following statements: PUT DATA(U,Y); PUT SKIP DATA(X): PUT SKIP DATA(W,V,Z);
