Assigns an I/O buffer to a text file.

Declaration

Target

Windows, Real, Proctected

Remarks

SetTextBuf should never be applied to an open file, although it can be called immediately after Reset, Rewrite, and Append.

If you call SetTextBuf on an open file once I/O operations have taken place, loss of data can result because of the change of buffer.

Borland Pascal does not ensure that the buffer exists for the entire duration of I/O operations on the file. A common error is to install a local variable as a buffer, then use the file outside the procedure that declared the buffer.
