CP
[Function] Compare the character strings in the columns specified in operands 1 and 2, and proceed to
the next step if the condition is satisfied.
If the condition is not satisfied, the program will proceed to the step next to the corresponding
ELSE command, if any, or to the step next to the corresponding EDIF command.
Comparison will be performed for the length set by a SLEN command.
If a character literal is specified in operand 2, comparison will be performed for the entire
length of the literal.
If the input condition is not satisfied and the ISXX command is not executed, the program will
proceed to the step next to the EDIF.
A maximum of 15 nests are supported when IFXX and DWXX are combined.
