5 # Load Floating-Point Single with Post-Update Shifted Indexed
13 EA <- (RA) + (RB)<<(SH+1)
14 FRT <- DOUBLE(MEM(RA, 4))
19 Let the effective address (EA) be the sum of the contents of
20 register RB shifted by (SH+1), and the contents of register RA.
22 The word in storage addressed by EA is interpreted as
23 a floating-point single-precision operand. This word is
24 converted to floating-point double format (see
25 page 138) and placed into register FRT.
27 EA is placed into register RA.
29 If RA=0, the instruction form is invalid.

35 # Load Floating-Point Double with Post-Update Indexed
49 Let the effective address (EA) be the sum (RA)+(RB).
51 The doubleword in storage addressed by EA is loaded
54 EA is placed into register RA.
56 If RA=0, the instruction form is invalid.
