GetLastError()

Gets the text of the last error generated by Maptitude.

The default value of the Reference Info option changed to "False" in Version 5.0.

text = GetLastError(array options)

Option	Type	Contents
Reference Info	Boolean	"False" (default) to have reference information, otherwise "True"

A string containing the text of the last error message, or null if there is no error message.

Use GetLastError() to get an appropriate message when trapping errors.
GetLastError() may not return an appropriate message if it is called after a Caliper Script function has returned successfully.
If the Reference Info option is "False" only the first part of the error message is returned. The "Click OK to continue" and "Reference info:" parts are not returned.
If the Reference Info option is "True" you can toggle whether to show the reference information with SetReferenceInfo().

on error do

ShowMessage(GetLastError({{"Reference Info", "False"}}))

Return()

end

CreateBuffers(...)
