# WriteInt (filehandle/stream, myinteger)

# Parameters

filehandle/stream = a valid variable set with the OpenFile, WriteFile command, or OpenTCPStream (v1.52+) 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)

# Description

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 Streams can only be used in Blitz Basic v1.52 or greater.

# Example

; Reading and writing a file using ReadInt and WriteInt functions
; Initialise some variables for the example
Int1% = 10 ; store 10
Int2% = 365 ; store 365
Int3% = 2147483647; store 2147483647 the largest positive Integer Value in BlitzBasic )
Int4% = - 2147483648 ; store -2147483648 the largest negative Integer Value in BlitzBasic )
; Open a file to write to
fileout = WriteFile("mydata.dat")
; Write the information to the file
WriteInt( fileout, Int1 )
WriteInt( fileout, Int2 )
WriteInt( fileout, Int3 )
WriteInt( fileout, Int4 )
; Close the file
CloseFile( fileout )
; Open the file to Read
filein = ReadFile("mydata.dat")
Read1 = ReadInt( filein )
Read2 = ReadInt( filein )
Read3 = ReadInt( filein )
Read4 = ReadInt( filein )
; Close the file once reading is finished
CloseFile( filein )
Print "Integer Data Read From File - mydata.dat "
Print Read1
Print Read2
Print Read3
Print Read4
