{title:Description}

This entry provides a quick reference for determining which method to use for
reading non-Stata data into memory.
See {hi:[U] 21 Inputting data} for more details.


{title:Summary of the different methods}


{title:{opt insheet} (see {help insheet})}

{phang}
1.  {opt insheet} reads text (ASCII) files created by a spreadsheet or
database program.

{phang}
2.  The data must be tab-separated or comma-separated, but not both
simultaneously, and cannot be space-separated.

{phang}
3.  A single observation must be on only one line.

{phang}
4.  The first line of the file can optionally contain the names of the
variables.

3.  A single observation can be on more than one line, or there can even be
multiple observations per line.


{title:{cmd:infix} (fixed format) (see {help infix})}

{phang}
1.  The data must be in fixed-column format.

{phang}
2.  A single observation can be on more than one line.

{phang}

{title:{cmd:infile} (fixed format){hline 2}infile with a dictionary (see {help infile2})}

{phang}
1.  The data may be in fixed-column format.

{phang}
2.  A single observation can be on more than one line.

    database files.

{title:{cmd:odbc} (see {help odbc})}

{phang}
1.  ODBC, an acronym for Open DataBase Connectivity, is a standard for
exchanging data between programs.  Stata supports the ODBC standard for
importing data via the {opt odbc} command and can read from any ODBC data
source on your computer.

{phang}
1.  {opt xmluse} reads Extensible Markup Language (XML) files{hline 2}highly
