QB64 Phoenix doesn't seem to like putting this one long line into a string variable. It just sits there with one CPU maxed out. Maybe it might do something eventually, but not in any reasonable time frame.
Is there an easy way using Linux to convert this long line into a file in the following format?
3
.
1
4
1
5
9
etc?
That should make it much easier to deal with.
While we are at it, what is the maximum size file that can be opened for reading?
I don't think there is a practical maximum on NTFS or EXT4 file systems. On FAT32 the largest file that can exist is 4gb's
I would just grab that file into a Byte Array.
DIM NUMBYTES AS _UNSIGNED _INT64
OPEN "PIFILE" FOR BINARY AS #1
NUMBYTES = LOF(1)
REDIM PIARRAY(0 TO NUMBYTES-1) AS _UNSIGNED _BYTE
GET #1,, PIARRAY()
' That part gets the file. If PI is an ASCII string then you can determine the place value of each digit by subtracting 48 from the Byte value.
PIARRAY(1) should be the decimal point IF the file has no leading spaces.
