Executes an operating system command from within ABL
that creates one or more new directories.
Syntax
OS-CREATE-DIR { dirname | VALUE ( expression ) }...
|
-
dirname
- The name of a directory to create. If the directory already
exists, no error is generated. If a file with this name exists,
an error is generated. The name can be a pathname or a simple name.
The directory name can contain Unicode characters. See OpenEdge
Development: Internationalizing Applications for more information
about Unicode.
If dirname is
not a fully qualified directory name, ABL prepends the current working
directory to dirname.
- VALUE
( expression )
- An expression that returns the name of a directory to create. Expression can
contain constants, field names, and variable names. The directory
name can contain Unicode characters.
Example
The
following procedure prompts the user for the name of a directory,
then creates it. If the name you give is not fully qualified, the
directory is created in your current directory.
r-os-dir.p
DEFINE VARIABLE stat AS INTEGER NO-UNDO.
DEFINE VARIABLE dir_name AS CHARACTER NO-UNDO FORMAT "x(64)"
LABEL "Enter the name of the directory you want to create.".
UPDATE dir_name.
OS-CREATE-DIR VALUE(dir_name).
stat = OS-ERROR.
IF stat NE 0 THEN
MESSAGE "Directory not created. System Error #" stat.
|
Notes
- The
directory name must conform to the naming conventions of the underlying
operating system.
- If a specified directory cannot be created, ABL returns an error code.
- Although an error can occur during execution of this statement,
the statement does not generate an error message, raise an error
condition, or affect the program's flow in any way. Check for an
execution error by using the OS-ERROR function and evaluating the return.
