REMARKS: EVAL command calculates the character string enclosed in the double quotes by regarding it as an expression. It can also calculate the character string assigned to a string variable or string array variable.

See Also: LFILES, SET PURPOSE: Displays names and attributes of specified file(s) on RAM disk. REMARKS: FI LES displays the filename, the filename extension (.BAS or other extension), and UP" (write-protection) attribute (see SET command). If no device name is specified, the last device name used will be assumed. If no filename is specified, all files on the specified device will be displayed. If neither device nor filename is specified, all files on the last device used will be displayed. To display a series of filenames, use an ambiguous filename. (See below.) To display a single filename, specify only that filename and its extension. The number of bytes used is also displayed. (See the SAVE and SET commands.) A maximum of three filenames will be displayed at one time, and an ¢ r n mark will appear to the left of the filenames.

Press I SHIFT I to move to the bottom of the previous page, and I SHIFT I [ ! ] to move to the top of the next page. Pressing C[J I ENTER Ior [ I J LTI when the ¢ mark is next to a desired filename CD allows the file to be loaded into memory. Pressing IENTER I or CD c::LJ kills (deletes) the file where the ¢ mark is located. Once a file has been deleted, it cannot be recovered, so use this option with care.
