; ; SD.ASM ; (revised 12/15/80) ; ; SUPER DIRECTORY PROGRAM ; by Bruce R. Ratoff ; ;Displays the directory of a CP/M disk, sorted alphabetically, ;with the file size in K, rounded to the nearest CP/M block size. ; ;This latest variation on a common theme will automatically adjust ;itself for any block size and directory length under CP/M 1.4 or 2.x ;or MP/M (any version). If the screen fills, program will pause until ;a key is struck (see NPL and LPS equates below). Total space used ;and number of files are printed at end. ; ;Command: SD FILENAME.FILETYPE or just SD ; ;Allows '*' or '?' type specifications. Drive name may also be ;specified. Ignores "SYS" files unless SOPT is TRUE and 'S' option ;is given (i.e., SD *.* S will print all files). ; ;12/15/80 Added space suppression when printing file ; totals. (KBP) ; ;12/14/80 Added logic to print space remaining on disk. ; Changed ^C test so that interrupting character is ; not echoed (makes remote use cleaner). (BRR) ; ;12/02/80 Fixed bug in print routine which compared last file ; against garbage before printing. (BRR) ; ;11/29/80 Changed to allow printing 4 file names. (Ben Bronson ; and Keith Petersen) ; ;11/22/80 Fixed bug in handling >256 files. Changed abort test in ; print routine to only abort on control-c.
