This may have been wished before but i cannot find it. I would love for the text I/O add-on to be able to return a error value when a file is not found rather than simply STOP. A simple wish but one that would be so useful.
Ideally I would like to be able to use a IF statement and PRINT an alert if the file cannot be found.
Currently if a gdl object refers to a text file it cannot find it will be displayed as a dot in the floor plan and have errors.
