Chapter 4 Macro FunctionScrEdit Software User Manual

4.4Error Messages

When compiling, it will shows errors in output window for user to find out easily. Some errors occur because of the user’s carelessness, sometimes just because the user misses an input command. Some errors will be found out easily in a short program. But that will be difficulty in a long Macro. To help the user debug, HMI editing software provides error messages when compiling program for reminding the user what the error is.

„Error messages when editing

„Code – 100: LABEL cannot be found

There is no such LABEL that GOTO designates.

„Code – 101: Recursion occurs

This error message is usually occurred in sub-macro. The ability of a sub-macro to CALL itself is called recursion. No matter it is called directly or indirectly. Basically, recursion cannot be adopted for sub- macro. The user can use GOTO or FOR (infinite times) to replace it.

„Code – 102: More than 3 nested FOR is used

This error message is to warn the user not to use more than 3 nested FOR commands. The purpose is to avoid insufficient memory. The user can use GOTO or IF to replace it.

„Code – 103: Sub-macro does not exist

This error message means that there is no sub-macro in the program. For example, CALL 5 means CALL sub-macro 5. If the user does not edit sub-macro 5 in the program, this error message will display to warn the user. The purpose is to warn the user to be more careful when editing (reduce input error or avoid forgetting editing the corresponding sub-macro) and prevent unexpected error.

„Code – 104: Number of NEXT is less than the number of FOR

Number of NEXT and FOR should match. This error code is used to remind the user to find the missing NEXT.

„Code –105: Number of FOR is less than the number of NEXT

Number of FOR and NEXT should match. This error code is used to remind the user if there is any missing FOR.

„Code–106: Repeated LABEL

This error message means that there are repeated LABEL in the same Macro. It means that when executing GOTO command, two different results will be generated and the program will be confusing with that. In order to avoid unexpected error, the user will get an error message during editing.
