A channel number, which identifies an opened file. This can be a hard coded constant or a variable. |

Data , data1 |
A variable who’s content are written to the file. |
When you write a variables value, you do not write the binary representatrion but the ASCII representation. When you look in a file it contains readable text.
When you use PUT, to write binary info, the files are not readable or contain unreadable characters.
Strings written are surrounded by string delimeters "". Multiple variables written are separated by a comma. Consider this example :
Dim S as String * 10 , W as Word
S="hello" : W = 100
OPEN "test.txt" For OUTPUT as #1
WRITE #1, S , W
CLOSE #1
The file content will look like this : "hello",100
Use INPUT to read the values from value.
