Hi all,
Reading the forum often gives you great ideas. I tried the file supplied by
Brian and got the following error, any idea why. I saved the file a test.ex

C:\EUPHORIA\include\dll.e:27 in function open_dll()
open_dll() is not supported in Euphoria for DOS32
    file_name = {107'k',101'e',114'r',110'n',101'e',108'l',51'3',50'2',
46'.',100'd',108'l',108'l'}

.. called from C:\PROGRA~2\TEMP\TEST2.EX:7

Global & Local Variables

 C:\EUPHORIA\include\machine.e:
    check_calls = 1

 C:\EUPHORIA\include\get.e:
    input_file = <no value>
    input_string = <no value>
    string_next = <no value>
    ch = <no value>

Thanks
Tony
