needed, which clearly identifies the file for subsequent file access.
The FreeFile function is used to create a free file handle. The handle is used as a parameter
for the Open instruction, which opens the file. To open a file so that it can be specified as a
text file, the Open call is:
Open Filename For Output As #FileNo
Filename is a string containing the name of the file. FileNo is the handle created by the
FreeFile function.
Once the file is opened, the Print instruction can be described line by line:
Print #FileNo, "This is a test line."
FileNo also stands for the file handle here. The second parameter specifies the text that is
to be saved as a line of the text file.
Once the writing process has been completed, the file must be closed using a Close call:
