What operating system are you using?

What shell are you using?

There is no loop in the above code. What loop are you talking about?

Please describe in English what you want the code:
Code:
[ $($APPEND+1) % 3 -eq 0 ]

to do and what values might be assigned to the variable APPEND. The code that you have here is extremely likely to give you a command not found error and a syntax error unless APPEND has not been assigned, has been assigned an empty string as a value, or has been assigned a string value such that that string value appended with the string +1 names an executable file on your command search path (in which case you'll get a syntax error from the % operator in your test command).
