Compiler Error Messages
Error Message Format
error C# : error description
(# is the error message number)
Example: error C37 : undeclared identifier : i
When there are compilation errors, refer to the error message number for a description of the error.
Error Description
(C1) syntax error：’identifier’
There are many possibilities that can cause a compilation error.
For example:
macro_command main()
char i, 123xyz // this is an unsupported variable name end macro_command
(C2) ‘identifier’ used without having been initialized
Macro must define the size of an array during declaration.
For example:
macro_command main()
char i
int g[i] // i must be a numeric constant
end macro_command
(C3) redefinition error : ‘identifier’
The names of variables and functions within their respective scopes must be unique.
For example:
macro_command main()
int g[10]，g // error
end macro_command
(C4) function name error : ‘identifier’
Reserved keywords and constants cannot be used as function names.
For example:
sub int if() // error
(C5) parentheses have not come in pairs
Statement missing “(“ or “)”.
For example:
macro_command main ) // missing “(“
(C6) illegal expression without matching ‘if’

The value following ‘case’ must be a constant.
For example:
macro_command main()
int a = 0
int b
select case a
case b // content following ‘case’ is not a constant
break
end select
end macro_command
(C12) ‘select’ statement contains no ‘case’
Missing ‘case’ in ‘select’ statement.
For example:
macro_command main()

break
end select
end macro_command
(C13) illegal expression without matching ‘select case’

Missing keyword ‘wend’.
The format of ‘while’ statement is:
while [logic expression]
wend
Any format other than this format will cause a compilation error.
(C24) syntax error : ‘break’

(C25) syntax error : ‘continue’
Illegal ‘continue’ statement. The ‘continue’ statement can only be used in ‘for’ or ‘while’ statement.

There should be no execution statement preceding a variable declaration.
For example:

(C95) total number of characters exceeds 100000
The total number of characters for a macro command should not exceed 100,000.
To utilize a macro command that exceeds the character limit, users need to adjust the command’s character count to be below 100,000 first. Once adjusted, the SYNC_TRIG_MACRO function can be employed to synchronously trigger the execution of other macro commands. This approach enables the successful execution of a macro command with a total character count exceeding 100,000.
