⎕NAPPEND Append data to a native file

The ⎕NAPPEND function is used to append data to the end of a tied file. The file must have been opened in a mode which permits writing. The data may be of any simple data type; nested and mixed arrays are not permitted. The data may be of any shape or rank but will be ravelled before writing to file.

The syntax of ⎕NAPPEND is :

          DATA ⎕NAPPEND TIENO {CONV} 

where CONV is an optional parameter specifying that the data should be converted to a different form before being written (see ⎕NWRITE for the conversion codes).

⎕NAPPEND is provided for compatibility with some other APL interpreters. The same facility is provided in a more general form by the ⎕NWRITE function.
