When the compiler encounters a syntax error it aborts the process for that script and displays a '''compiler error message''' in the [[Log window panel|Log window]].

There are a couple of guidelines to remember when trying compiler error message
* The compiler reports the error when it can no longer make sense of the script: this often occurs on the line ''after'' the line containing the error.
* Several error messages end with "''while compiling <include>.nss''" even though the error is normally in the script being compiled not the included script.

; Break outside of loop or case statement (while compiling <include>.nss)

=== E ===
; Equality test has invalid operands (while compiling <include>.nss)
: [explanation]
: The include file is not normally the source of the error.










=== M ===
; Mismatched types (while compiling <include>.nss)
# The return type not matching function
# A void function has been assigned to a variable, for example void function assigned to variable, string function assigned to int variable
: The include file is not normally the source of the error.

=== N ===
; No colon after case label : [explanation]

; No left bracket on arg list

# A function does not have a return statement.
# One or more of logic branches in a function does not have a return statement.
# A function does not have an else or default case with a return function.
: The include file is not normally the source of the error.


=== P ===
; Parsing variable list
: The statement terminator (;) is missing from the on previous line





=== U ===
; Undefined identifier (<identifier>)
# A variable is being used before it is defined
# A string is missing its opening double-quotes mark

# A line contains a rouge double-quotes mark

=== V ===
