VISICALC COMMAND CHART
BY: NIGHT HAWK
*----------------------*
/B SET AN ENTRY TO BLANK
/C CLEARS THE SHEET, SETTING ALL ENTRIES TO BLANK
/D DELETES THE ROW(/DR) OR COLUMN(/DC) ON WHICH THE CURSOR
LIES.
/E ALLOWS EDITING OF THE ENTRY CONTENTS OF ANY ENTRY POSITION
BY REDISPLAYING IT ON THE EDIT LINE. USE <- -> KEYS & ESC.
/F SETS THE DISPLAY FORMAT OF AN ENTRY TO ONE OF THE FOLLOWING
FORMATS:
/FG GENERAL
/FI INTEGER
/F$ DOLLAR AND CENTS
/FL LEFT JUSTIFIED
/FR RIGHT JUSTIFIED
/F* GRAPH
/FD DEFAULT
/G GLOBAL COMMANDS. THESE APPLY TO THE ENTIRE SHEET OR WINDOW.
/GC SETS COLUMN WIDTH
/GF SETS THE GLOBAL DEFAULT FORMAT
/GO SETS THE ORDER OF RECALCULATION TO BE DOWN THE
COLUMNS OR ACROSS THE ROWS
/GR SETS RECALCULATION TO BE AUTOMATIC(/GRA) OR MANUAL(/GRM).
/I INSERTS A ROW(/IR) OR A COLUMN(/IC)
/M MOVES AN ENTIRE ROW OR COLUMN TO A NEW POSITION.
/P PRINT COMMAND
/R REPLICATE COMMAND
/S STORAGE COMMANDS ARE AS FOLLOWS:
/SS SAVE
/SL LOAD
/SD DELETES SPECIFIED FILE ON DISK
/SI INITIALIZE A DISK ON SPECIFIED DRIVE
/SQ QUITS VISICALC
/T SETS A HORIZONTAL TITLE AREA(/TH), A VERTICAL TITLE AREA
(/TV), SET BOTH A HORIZONTAL & VERTICAL TITLE AREA(/TB)
OR RESETS THE WINDOWS TO HAVE NO TITLE AREAS(/TN)
/V DISPLAYS VISICALC'S VERSION NUMBER ON THE PROMPT LINE
/W WINDOW CONTROL
/WH HORIZONTAL WINDOW
/WV VERTICAL WINDOW
/W1 RETURNS SCREEN TO ONE WINDOW
