s2

•Compares s1 and s2 as unsigned numbers, and

if s1 is less than s2, it enters the continuity status (on) and

if s1 is greater than or equal to s2, enters the noncontinuity status (off).

• When s1 and s2 are words:

0 to 65535 (decimal) or H0000 to HFFFF (hexadecimal)

When s1 and s2 are double words: 0 to 4294967295 (decimal) or H00000000 to HFFFFFFFF (hexadecimal)
