Further credit goes to Brian Lee, the product manager, who was very involved in guiding the look-and-feel and the overall functionality of the program. Thanky you so much Mr. Lee, we really appreciate your help, then and now. :-)\\

!!Private Notes
!!Findings from Mike Silva:
Zero page\\
\\
$95 Current Spreadsheet Row (all rows and columns are zero-based)\\
$96 Current Spreadsheet Column\\
\\
$99 Current Screen Y\\
$9A Current Screen X\\
\\
$9F Current Cell Data Pointer (points to data of current cell)\\
\\
$A7 Last Spreadsheet Row\\
$A8 Last Spreadsheet Column\\
\\
$CA Last Added Cell Data Pointer (a stack pointer to next free memory to add new cell data) More below #1\\
\\
Non-zero page\\
\\
$1901 Array of column widths\\
\\
$19DB Last direction of cursor movement (1=left, 2=right, 3=up, 4=down)\\
\\
$1A00 Screen memory\\
\\
$2BF3 Array of 3-byte cell structures. Each structure consists of a 2-byte cell data address, followed by one additional byte (more below #2). Array order is A1, B1, C1,...n1, A2, B2, C2,...n2,...Am, Bm, Cm,...nm where n is last sheet column, m is last sheet row.\\
\\
#1 Cell data is form B1, B2, B3, cell data (variable number of cell data bytes).\\
B1: D7-D6 = number format code\\
D5 = comma flag\\
D4 = dollar flag\\
D3 = percent flag\\
D2 = ??? haven't figured this one out\\
D1-D0 = sign code\\
B2: D7-D6 = justify code\\
D5-D4 = ??? haven't figured this one out\\
D3 = protect value flag\\
D2-D0 = margin value 0-7\\
B3: D7 = protect entry flag\\
D6-D0 = length of cell data that follows\\
\\
Cell data is either text or ATARI numeric. In formula cells the value of the formula is first, followed by the actual formula.\\
\\
#2 Additional cell info byte\\
D7-D6 = cell type (01 = text, 10 = numeric, 00 = empty cell?)\\
D5-D2 = precision value\\
D1-D0 = ???\\
\\
The cell data stack grows downward from $7FFF on a 48k machine. By testing other hardware it will be possible to see where the stack begins in different memory circumstances, and also perhaps to ID some other addressing bits in the cell pointer array, bits that are just zero in the base 48k version.\\
!!Problems when importing VisiCalc files ; findings from luckybuck
SynCalc holds an import program, called: 'VC->SC' in order to read in files from the VisiCalc program. All versions(!) out there, except the original ones are not able to import properly VisiCalc files! The SynCalc program tries to load a convert program from the original program disk. If this fails, you get the following pictures:
[{Image src='1.jpg' width=330 height=200 }]
SynCalc VC->SC option selected\\
\\
[{Image src='2.jpg' width=332 height=202 }]
SynCalc asking for the program master disk\\
\\
[{Image src='3_.jpg' width=333 height=201 }]
SynCalc failed to load a program from the program master disk\\
\\
Further, if you have really hard VisiCalc spreadsheets and the 1985 version even in original form fails to import, try the 1983 version, which works like a charm in these very rare cases.
