 Pseudo-code:
 
-    EA <- (RA) + (RB)
+    EA <- (RA) + (RB)<<(SH+1)
     FRT <- DOUBLE(MEM(RA, 4))
     RA <- EA
 
 Description:
 
-    Let the effective address (EA) be the sum (RA)+(RB).
+    Let the effective address (EA) be the sum of the contents of
+    register RB shifted by (SH+1), and the contents of register RA.
 
     The word in storage addressed by EA is interpreted as
     a floating-point single-precision operand. This word is
