Freefile

Format

freefile
freefile ( )

Description

BASIC256 allows for multiple files to be opened at a single time. The freefile function returns a free file number that you can use in your next Open or Openb. Once a file is closed, freefile will return that file number to the list of available file numbers and may reissue that number.

Example

# copy one binary file to another
k = 0
source = freefile
openb source,"file.pdf"
dest = freefile
openb dest,"file_copy.pdf"
reset dest
while not eof(source)
   writebyte dest, readbyte(source)
   k++
end while
close dest
close source
print k + " bytes copied."
