MMEMory Subsystem
The MMEMory (mass memory) subsystem provides commands which allow for access to the storage
media of the instrument and for storing and loading various instrument settings.
The various drives can be addressed via the "mass storage unit specifier" <msus> using the conven-
tional DOS syntax. The internal hard disk is addressed by "C:". For details on drives refer to chapter 4
"Instrument Functions - Basic Settings", section "Saving and Recalling Settings Files - FILE Key".
The file names <file_name> are indicated as string parameters with the commands being enclosed in
quotation marks. They also comply with DOS conventions.
DOS file names consist of max. 8 ASCII characters and an extension of up to three characters
separated from the file name by a dot "." Both, the dot and the extension are optional. The dot is not
part of the file name. DOS file names do not distinguish between uppercase and lowercase notation. All
letters and digits are permitted as well as the special characters "_", "^", "$", "~", "!", "#", "%", "&", "-",
"{", "}", "(", ")", "@" and "`". Reserved file names are CLOCK$, CON, AUX, COM1 to COM4, LPT1 to
LPT3, NUL and PRN.
The two characters "*" and "?" have the function of so-called "wildcards", i.e., they are variables for
selection of several files. The question mark "?" replaces exactly one character, the asterisk means any
of the remaining characters in the file name. "*.*" thus means all files in a directory.
