MAKELRESULT
MAKELRESULT(ERROR_NUM, ARG_NUM)
MAKELRESULT is used to assign appropriate return values to a function in the case of an error. The return value has two components: an error code and an index:
Parameter
Description
ERROR_NUM
The number of the entry, in the array of error messages, to return as the error message.
ARG_NUM
The index of the argument around which a red circle must be placed.
To create the error message table, make the following string array:
char * myErrorMessageTable[NUMBER_OF_ERRORS] =
{
"interrupted",
"insufficient memory",
"must be real",
etc...
};
A call to MAKELRESULT(3,1) displays the third string, "must be real" under the first argument of the custom function.
* 
The error message table must be registered with the CreateUserErrorMessageTable function for it to be used by MAKELRESULT.
