N_XMEMOWIDTH()
Set the maximum length of a variable length field

Syntax
N_XMEMOWIDTH([<nLength>])

RDD Syntax
SET MEMOWIDTH TO <nLength>

Argument
<nLength> is the maximum length for a variable length field. When creating a 
new Btrieve file with a memo field, RaSQL uses the value set by MEMOWIDTH as 
the maximum length of the variable length field, as needed when the file is 
subsequently USEd. The default value is 1024. You should set the value as 
low as is realistic; doing so will not save any more disk space, but it will 
use memory more efficiently.

Returns
Current setting.

Remarks
Used in conjunction with COPY TO, COPY STRUCTURE TO, or CREATE FROM where 
the target file is a Btrieve file.

Note
Btrieve limits you to one memo field per record, and it must be the last 
field in the record.
