- <h3 class="subsection">1.6.4 File Format Errors</h3>
- <p>Certain application crashes result from an application not adhering
- to the required conventions about data and file formats, or because the
- application was invoked in the wrong mode (<a href="Modes-of-Operation.html#Modes-of-Operation">Modes of Operation</a>). These
- are the following.
- </p>
- <dl compact="compact">
- <dt> <code><var>application-name</var>: invalid text format (code <var>nn</var>)</code></dt>
- <dd><a name="index-invalid-text-format"></a>
- <p>An application that was expected to return a string of characters to
- be written to a text file returned data that did not correspond to any
- valid character representation.
- </p></dd>
- <dt> <code><var>application-name</var>: null character in prompt</code></dt>
- <dd><p>An interactive application (invoked rightly or wrongly with ‘<samp>-i</samp>’,
- ‘<samp>-t</samp>’, or ‘<samp>-s</samp>’) is required to exchange strings of non-null
- characters internally with <code>avram</code>, and used a null.
- </p></dd>
- <dt> <code><var>application-name</var>: invalid file name (code <var>nn</var>)</code></dt>
- <dd><p>The data structure representing a file obtained from an application
- has a name consisting of something other than character strings. This
- error could be the result of a filter mode application (<a href="Filter-Mode.html#Filter-Mode">Filter Mode</a>) being invoked in parameter mode.
- <br>
- (<a href="Parameter-Mode.html#Parameter-Mode">Parameter Mode</a>)
- </p></dd>
- <dt> <code><var>application-name</var>: null character in file name</code></dt>
- <dd><a name="index-null-character-in-file-name"></a>
- <p>Similar to the above errors.
- </p></dd>
- <dt> <code><var>application-name</var>: bad character in file name</code></dt>
- <dd><a name="index-bad-character-in-file-name"></a>
- <p>Slashes, backslashes, and unprintable characters other than spaces are
- also prohibited in file names.
- </p></dd>
- <dt> <code><var>application-name</var>: invalid output preamble format</code></dt>
- <dd><a name="index-invalid-output-preamble-format"></a>
- <p>According the format used by <code>avram</code> for data files, a data file
- may contain an optional text portion, known as the preamble. This
- error occurs when a data file obtained from an application can not be
- written because the preamble is something other than a list of
- character strings.
- </p></dd>
- <dt> <code><var>application-name</var>: invalid file specification</code></dt>
- <dd><a name="index-invalid-file-specification"></a>
- <p>This error occurs in situations where the data structure for a file
- obtained by evaluating the application is too broken to permit any
- more specific diagnosis.
- </p></dd>
- <dt> <code>avram: invalid raw file format in <var>application-name</var></code></dt>
- <dd><a name="index-invalid-raw-file-format"></a>
- <p>The file containing the virtual machine code was not able to be
- loaded, because the code was not in a recognizable format. Either the
- file has become corrupted, the compiler that generated it has a
- bug in it, or the wrong file was used as a virtual code file.
- </p></dd>
