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) |
|
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. |

; 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 WaitKey() |
