filehandle/stream = a valid variable set with the OpenFile, WriteFile command, or OpenTCPStream (v1.52+)
|
|
<br />
|
|
myinteger = an integer variable (a floating point number can be used but this will be converted to an integer before saving so only the integer part will be saved)

Once you've opened a disk file (or stream) for writing, use this command to write a single integer value to the file. Note, each value written uses 4 bytes and is written least significant byte first. The range of the value saved is -2147483648 to 2147483647
|
|
|
|
<br />
|
|
|
|
<br />
|
|
Streams can only be used in Blitz Basic v1.52 or greater.
