LOAD Sentence question

[#1]

Hi all,

Checking LOAD documentation, it says:

fieldref ::= ( fieldname |@fieldnumber |@startpos:endpos [ I | U | R| B ] )

What about them? How can I apply this syntax in my load code?

LOAD Field U as CustomField,

FROM Table.

QlikView syntax shows as invalid.

Any comment?

Regards,

Ricardo
