Dialog For Choosing File Names

Description
Displays a browser dialog in which the user chooses a file. This routine differs from the openfile , savefile routines in that the browser will start in the directory where the default file is located.

The character row vector caption specifies the caption for the dialog. The caption must begin with one of the following words: "Read", "Load", "Open", "Write", "Store", or "Save". The character row vector default specifies the default file name. This name may contain the entire path that specifies the file from the root directory, or it may specify the file relative to the current directory. If the second character of default is a colon, the first character in default specifies a disk drive. No other character in default can be a colon. The character row vector description describes the type of files that the argument extension refers to (for example description might equal "data files"). The character row vector extension specifies a file extension (for example "*.dat"). The list of files displayed in the dialog is limited to those with this extension.

The return value of chfile is a character row vector containing the name of the file that the user chooses. This is a complete path name including the disk drive. If the user chooses the Cancel button in the dialog, an empty character row vector is returned; i.e., its column dimension is zero.
