<source_file> is the name on the Appx server that you want to transfer to the user's PC (Required). This must be a file readable by user 'appx' (Linux/Unix) or the current user (Windows).

<convert_flag> indicates if any file conversion is required (Optional). If zero or not passed, then no conversion will be done. A value of 1 means convert the file automatically based on the filename extension. A value of 2 means convert the file automatically based on the contents of the file (ie, it won't convert binary files). A value of 3 means do the conversion regardless of file type.

<convert_flag> indicates if any file conversion is required (Optional). The allowable values are:

NO - no conversion will be done. This is the default if not PASSed.
AUTO-EXT - convert the file automatically based on the filename extension.
AUTO-CONTENT - convert the file automatically based on the contents of the file (ie, it won't convert binary files).
YES - Do the conversion regardless of file type.

If conversion is requested, this routine will make a temporary copy of the file, converting as necessary, then upload the converted file. The temporary copy will be deleted. The temporary copy is created in the applications 'Tmpdata' folder, same as the working files for a restructure.

If a <convert_flag> of 2 is passed, the routine will read approximately the first 1000 bytes of the file and look for characters in the range ASCII 0 to 9 (0x00 to 0x09), or ASCII 14 to 31 (0x0e to 0x1f). If any are found, the file is assumed to be binary and no conversion will take place.

If a <convert_flag> of AUTO-CONTENT is passed, the routine will read approximately the first 1000 bytes of the file and look for characters in the range ASCII 0 to 9 (0x00 to 0x09), or ASCII 14 to 31 (0x0e to 0x1f). If any are found, the file is assumed to be binary and no conversion will take place.

If the file is determined to be a text file (either by extension or the lack of binary characters), the routine looks for the presense of a CR/LF pair in the first ~1000 characters of the source file to determine if it's in Unix or Windows format and then uses the following matrix to decide if the file really needs to be converted:
