Example 1: Extracting the parts of a file name

This program uses the file functions to extract the directory name, the base name, the root name, and the file extension:

IMPORT os
MAIN
  DISPLAY "Dir name   = ", os.Path.dirName(arg_val(1))
  DISPLAY "Base name  = ", os.Path.baseName(arg_val(1))
  DISPLAY "Root name  = ", os.Path.rootName(arg_val(1))
  DISPLAY "Extension  = ", os.Path.extension(arg_val(1))
END MAIN

Example results:

Table 1. Example results
Path	os.Path.dirname	os.Path.basename	os.Path.rootname	os.Path.extension
`.`	`.`	`.`		`NULL`
`..`	`.`	`..`	`.`	`NULL`
`/`	`/`	`/`	`/`	`NULL`
`/usr/lib`	`/usr`	`lib`	`/usr/lib`	`NULL`
`/usr/`	`/`	`usr`	`/usr/`	`NULL`
`usr`	`.`	`usr`	`usr`	`NULL`
`file.xx`	`.`	`file.xx`	`file`	`xx`
`/tmp.yy/file.xx`	`/tmp.yy`	`file.xx`	`/tmp.yy/file`	`xx`
`/tmp.yy/file.xx.yy`	`/tmp.yy`	`file.xx.yy`	`/tmp.yy/file.xx`	`yy`
`/tmp.yy/`	`/`	`tmp.yy`	`/tmp.yy/`	`NULL`
`/tmp.yy/.`	`/tmp.yy`	`.`	`/tmp.yy/`	`NULL`

These examples use UNIX™ file names. On Windows™ the result would be different, as the file name separator is a backslash (\).
