Note In CS1-H, CJ1-H, CJ1M, and CS1D (for Single-CPU System) CPU Units,
these Flags are left unchanged.
In CS1 and CJ1 CPU Units, these Flags are turned OFF.
Do not program another instruction between CMPL(060) and an input condi-
tion that accesses the result of CMPL(060) because the other instruction
might change the status of the Arithmetic Flags.
When CIO 000000 is ON in the following example, the eight-digit unsigned
binary data in CIO 0011 and CIO 0010 is compared to the eight-digit
unsigned binary data in CIO 0009 and CIO 0008 and the result is output to
the Arithmetic Flags. The results recorded in the Greater Than, Equals, and
Less Than Flags are immediately saved to CIO 000200 (Greater Than),
CIO 000201 (Equals), and CIO 000202 (Less Than).
