The Single Word Write List (SFWR) instruction adds the input single word to the list structure. The Double Word Write List (SFWRD) writes double words, while the Floating Point Write List (SFWRF) writes floating points.

A list consists of n elements plus n elements. For single word lists, n occupies one single word register, while for double word and floating-point lists, n occupies two registers to store them as double words. Ensure that the total length of the list structure does not exceed the given limit.

For example, SFWR K100 D10 K5 writes the word 100 into a list starting with D10. The space occupied by the list will not exceed the range of D [10... 14].

SFWRD K123456 D10 K5, write the doubleword 123456 into the list starting with D10, paying attention to the number of elements occupying two registers. The space occupied by the list will not exceed the range of D [10... 19].

图2 List Write Double Word

SFWRF K1.23 D10 K5, write floating point 1.23 into the list starting with D10, paying attention to the number of elements occupying two registers. The space occupied by the list will not exceed the range of D [10... 19].
