Only files with a text based FILEKIND can be included in the files specified for inclusion. Text based FILEKIND are files with FILEKIND BACKUPPRINTER and most files with FILEKIND value greater or equal to ALGOLSYMBOL (refer to the FILEKIND section of the File Attributes Programming Reference Manual.)

An error is given for other FILEKINDs and no operation is performed. For example, FILEKIND COBOL74 is allowed, but COBOL74CODE is not allowed.

An error is given if files with filenames containing illegal characters are included in the set of files specified.

The legal characters are described in the previous descriptions of the MCPNATIVE and JOLIET options.

An error is given if the files specified constitute a directory structure that is not supported by the ISO 9660 standard, such as trying to include a file and a directory with the same name. For example, if you have files named DATA/A and DATA/A/OLD, then attempting to include DATA/= on a CD fails.

Only files with a FIXED BLOCKSTRUCTURE can be included in the files specified for inclusion.

An error is given if record-oriented files (MCP file with a FILECLASS attribute of RECORDORIENTED) with odd record lengths are included in the set of files specified. For MCP files, this generally refers to files with an odd record length specified in the MAXRECSIZE attribute and a value of 8 specified in the FRAMESIZE attribute. This restriction conforms to ISO 9660 standards.

Specifying MCPNATIVE for files of FILEKIND BACKUPPRINTER does not prevent their conversion to an ASCII format. FILEKIND BACKUPPRINTER is not supported on CD.
