Input comparison instructions cannot be used as right-hand instructions, i.e.,
another instruction must be used between them and the right bus bar.

When CIO 000000 is ON in the following example, the floating point data in
words D00100 to D00103 is compared to the floating point data in words
D00200 to D00203. If the content of D00100 to D00103 is less than that of
D00200 to D00203, execution proceeds to the next line and CIO 005000 is
turned ON. If the content of D00100 to D00103 is not less than that of D00200
to D00203, execution does not proceed to the next instruction line.

This section describes instructions used to handle table data, stacks, and
other ranges of data. The 5 instructions at the bottom of the table (marked
with an asterisk) are supported by the CS1-H, CJ1-H, CJ1M, and CS1D CPU
Units only.
