|Part of Error module
| Error.LastMsg : string
| Error.LastMsg is a function that returns the error message set by the last called predefined subprogram. If there is no error, then it returns the empty string. If there is an error, you can use Error.Last to obtain the error code.
The fact that Error.LastMsg is not "" does not necessarily mean that the previous predefined function failed or failed completely. Error.LastMsg also returns a number of warning messages. For example, if a user specifies a number larger than maxcolor for the color parameter of the Draw.Line procedure, the line is still drawn, only in color maxcolor. However, Error.LastMsg will return a message that indicates that the color was out of range
| This program creates the directory called information. If the creation fails, it prints out the error number and an error message.
Dir.Create ("testdata/information") if Error.Last = eNoError then put "Directory created" else put "Did not create the directory." put "Error Number: ", Error.Last put "Error Message: ", Error.LastMsg end if
| Exported qualified.
This means that you can only call the function by calling Error.LastMsg, not by calling LastMsg.
