The ReadInt function will read the next integer (32bit) from an open file channel.
FACTS:
* ReadInt only works with files opened with ReadFile command.
* Integer values range from -2147483647 to 2147483647
Mini Tutorial:
This example creates a simple file with some various bits of data store in it, then read it's back again.
File$=TempDir$()+"PB_TestFile.txt"
; CReate a File for writing data to
WriteFile File$,1
; Write a Byte to file channel 1, of value 200
WriteByte 1,200
; Write a Word to file channel 1, of value 64000
WriteWord 1,64000
; Write a INTEGER to file channel 1, of value 123456
WriteInt 1,123456
; Write a FLOAT to file channel 1, of value 123.456
WriteFloat 1,123.456
; Write a String to file channel 1, of value Hello World
WriteString 1,"Hello Word"
; Close this file channel
CloseFile 1
Print "============================"
Print "Reading File:"+File$
Print "============================"
; Open a file to READ with READFILE
ReadFile File$,1
; Read and display the byte value
Print " Byte Data:"+Str$(ReadByte(1))
; Read and display the word value
Print " Word Data:"+Str$(ReadWord(1))
; Read and display the Integer value
Print "Integer Data:"+Str$(ReadInt(1))
; Read and display the Float value
Print " Float Data:"+Str$(ReadFloat(1))
; Read and display the String value
Print " String Data:"+ReadString$(1)
; Close this file channel
CloseFile 1
If FileExist(file$) Then DeleteFile file$
; Display the screen and wait for a key press
Sync
WaitKey

This example would output.
============================
Reading File:C:Windows\temp\Pb_TestFile.txt
============================
Byte Data:200
Word Data:64000
Integer Data:123456
Float Data:123.456
String Data:Hello World
