Hello,

I am having another problem in my program once I compare the second value of the FCB string $11 it is suppose to JMP to the operation add_op and perform the action something is wrong it never JMP? Any ideas?

Thank you,

Andrew

[ZhangJennie · Accepted solution]

the  A1103 means "The label specified in front of a comment or an assembly instruction or directive, is detected twice in a source file."

please change CLR_OP to other name such as CLR_OP_1 to see if this can fix the problem.

Hope this helps
