; ;
; Switch Directory - DOS (SD) is a utility that allows easy ;
; switching between subdirectories and drives with a minimum of ;
; typing. SD has been designed to replace the DOS CD command ;
; while providing enhancements to the CD command. SD allows you ;
; to specify a specific subdirectory name, a combination of ;
; subdirectory names and search switches or a complete path ;
; specifier. All features of SD work across disk drives. If ;
; you have made a mistake, hitting Ctrl-Brk while SD is searching ;
; will break you out of SD and put you back in the subdirectory ;
; you started in. ;
; ;
; Switch Directory - DOS 1.0 is descended from SD version 3.4 and ;
; its predecessors. The improvement in SD is that SD - DOS can ;
; attach itself to DOS and provide the same functionality ;
; previously only available with SD in combination with PCED or ;
; CED. For users of PCED or CED, an enhanced version of SD 3.4 ;
; is available called Switch Directory - CED. ;
; on your disk drives. ;
; ;
; ;
; Usage: [d:\....]>SD [drive][command specification] ;
; ;
; Commands: ;
; ;
; During startup - ;
; with + no help ;
; with - no internal stack ;
; can also put configuration file on command line ;
; ;
; During normal use - ;
; \ - switch to specific path ;
; / - search below subdirectory ;
; these switches can be mixed ;
; ie. sd \turbo/source\myprog would be legal ;
; @ - switch to last path selected with "# ;
; @" - kill SD and release memory ;
; "+ or - - go to next highest or lowest path ;
; "#=[path] - store [path] in stack location # ;
; "#=@ - insert current path into stack location # ;
; "# - switch to entry number # ;
; "s - display stack ;
