Filename

A filename is specified as a C-language string. This string has to follow some rules:

x x x x x x x x . y z z

NULL

1. length string = 12

2. x = character of the base name formed by max 8 characters

3. y = kind of file (= 1 character)

’s’

standard file

’c’

custom file

4. z = file index (= 2 characters: 0..9)

zz specifies the location in memory where the file is stored.

- for standard files: zz = 00...maximum standard files

- for custom files: zz = 00...63 where 00 is reserved for the file ’none .c00’ (file which is loaded when no signal is applied)

5. yzz is a unique combination. In other words, no two files can exist with the same extension yzz.

To specify more than o ne file you can use the question m ark (?) and (*) wild card character for x, y and z (o r

any other character).

?: This wildcard charac ter can represent any p ossible cha racter on a particular location.

* : This wildcard character can represent any possible character(s) following the wildcard’s position in the

string.

•”ntsc .c01”

•”svga_60v.s?7”

•”????????.???”

• ”sv*.*”
