FILENAME$
Field of Application Function returning the names of the fi les stored in the specifi ed part
of the printer’s memory.
Syntax FILENAME$[(<sexp>)]
<sexp> is the name of the memory device from which the fi rst
fi le name (in alphabetical order) will be listed. Parts of
fi le names and wildcards (*) are allowed. Maximum size
is 30 characters.
If <sexp> is omitted, the next fi le name in the same memory
device is listed. Can be repeated. When there are no fi les left
to list, the output string will be empty.
Remarks
The specifi ed memory device must be mounted. The fi le name must
correspond to the name of the fi le stored in the memory device in regard of
upper- and lowercase characters. Wildcards (* = ASCII 42 dec.) can be used.
The list may include all type of fi les. Even system fi les, that are preceded by
a period character (for example .FONTALIAS), may be listed. No device
names are included in the listed fi le names.
Example This example shows how all fi les in "rom:" with the extension .PRG
are listed:
10 FNAME$ = FILENAME$("rom:*.PRG")
20 WHILE FNAME$<> ""
30 PRINT FNAME$
40 FNAME$ = FILENAME$
