Re: Are SDF & ASCII same?

SDF (System Data Format) is a format that came into common use when PCs 
expanded the community of computer and software users. ASCII was the 
'native' format for those early personal computers based on 8-bit and 
16-bit microcomputers.

SDF files were commonly used for im****ting and ex****ting data between 
applications, such as Lotus 1-2-3 and desktop database apps (Btrieve, 
Xtrieve). The SDF file format is one record per line, with fields 
delimited by commas. Text values are enclosed in "". Field ordering in 
each record must be consistent. Two commas in a row indicate a field 
value is null. Files in that format often used the .SDF extension.

For a file in that format today, many products use the term 
comma-delimited or CSV (comma-separated values). Some products sup****t a 
CSV format that includes metadata (field names) in the first record 
(first line) of a file.
