ISXX (String Comparison)
[Function]
Compares the character string in the column numbers in Operand 1 and Operand 2. When the condition
is established, the program proceeds to the next step. When the condition is not established, if there is a
corresponding ELSE command, the program proceeds to the next step after that. If not, it proceeds to
the next step after the corresponding EDIF command. The length of the string to be compared is set by
the SLEN command. If there is a literal character in either Operand 1 or Operand 2, the length to be
compared is that of the literal character. When the input condition is not established and there is no IF
XX
command executed, the program proceeds to the step following the corresponding EDIF. Up to 15
levels of nesting are available when IS
XX
and DW
XX
are combined.

Column 1 ~ 4 is to select Axis 1, Axis 2 and column 5 ~ 8 is to select the jog direction.
When flag 600 is OFF, nothing is done and the program proceeds to the step after the last EDIF.
When column 1 ~ 8 contains the data shown below, Axis 1 moves forward.
