==={{header|Applesoft BASIC}}===

Apple DOS 3.3 has a flat filesystem with no concept of directories. DOS commands such as RENAME are run directly from the Applesoft prompt but are not technically part of Applesoft BASIC. Thus, attempting to add this line to a program and run it results in a syntax error on that line.

 

 

To use a DOS command from a program, use the BASIC statement PRINT followed by CHR$(4) and the string containing the DOS command.

 

 

Apple ProDOS does have directories. To change the current working directory to the "root" directory, issue a PREFIX / command.

 

20 PRINT CHR$ (4)"RENAME DOCS,MYDOCS"

30 PRINT CHR$ (4)"PREFIX /"

=={{header|PARI/GP}}==

GP has no built-in facilities for renaming, but can use a system call:

system("mv /input.txt /output.txt");

system("mv docs mydocs");

PARI, as usual, has access to all the standard [[#C|C]] methods.

 

Alternatively it's possible to bind rename() system call to a new function:

 

=={{header|Pascal}}==

f : file ; // Untyped file

begin

Rename(f,'\mydocs');

 

=={{header|Perl}}==

use File::Spec::Functions qw(catfile rootdir);

# here

# root dir

move (catfile rootdir, 'input.txt'), (catfile rootdir, 'output.txt');

 

The core <code>rename($oldfile,$newfile)</code> can rename a file within a directory, but has the usual limitations of the <code>rename()</code> system call or C library function, which means generally not working across filesystems, and perhaps not working to rename directories. <code>move()</code> does a copy and delete when necessary.
