To write text to a file:
Use the [File->Write] tag. The file object should be cast with an open mode that permits writing. The example below adds the text This is some text after the fifth line of the file.
[Var:'File'=(File: 'myfile.txt', File_OpenWrite, File_ModeLine)]
[$File->(SetPosition: 5)]
[$File->(Write:'this is some text')]
[$File->Close]
To write part of a string variable to a file:
Use the [File->Write] tag with the optional size and offset integer parameters. This is useful for truncating part of an existing string variable on
[Var:'Text'='There are five elements']
[Var:'File'=(File: 'myfile.txt', File_OpenWrite, File_ModeLine)]
[$File->(Write: $Text, 4, 10)]
[$File->Close]
