MMEMory Subsystem
3–82 AM700 Audio Measurement Set Programmer Manual
The upper level of the AM700 files comprise ROM, NVRAM, and DOS logical
directories. Under those, other directories or files may exist. Certain directories are
accessible by the user for storage use or information. Certain other directories are
accessible by AM700 operating system firmware only.
The AM700 allows an optional mass storage unit specifier (a logical directory
name) with any file name given to the MMEMory commands. The syntax of the file
name is as follows:
[device:]{/path_name/path_name/}<filename>
The device and path portions are optional and not needed if the <filename> is in
the current working directory. “device” can be one of “rom”, “nvram”, or “dos”.
The <filename> parameter in the MMEMory subsystem is a string. The contents
of the string are dependent on the needs of the format of the mass storage media. In
particular, the file name may contain characters for specifying sub–directories (that
is, \ for DOS, / for UNIX) and the separator for extensions in DOS (that is a period).
File names may be absolute, rooted, or relative. Absolute file names use the
complete name with device and total path to the file. Rooted file names use the path
within a designated device and may be used after changing directory to that device.
Relative file names are assumed to be in the current working directory.
Note that this syntax places some restrictions on the <filename> (for example,
commas are not allowed).
The Storage Manager system of the AM700 permits a total of 250 file names
maximum in each list for Function files or other user files in a directory.
