A macro question.

I have action:Transfer Text

with the following settings:
------------------------------------
Transfer Type: import Fixed Width
Specification Name: ??
Table Name: parts
FileName: C:\test\parts.t xt
Has Field names: No

So what is the Specification name imply. The text file which I will be
transfering could be space or tab delimited. I do not know at this
point. But would like to know what the specification name will be for
the 2 types ie space or tab delimited text file.

Thanks,
Sa
