Function

Usage

for name in dmm.buffer.catalog() do...end

name

A string representing the name of a user created DMM reading buffer

Details

You can access the catalog for the user-created local reading buffers so that you can print the names

of all reading buffers in the system. The entries are enumerated in no particular order. From this list,

you may selectively delete reading buffers from the system.

Do not delete the reading buffers by sending:

for name in dmm.buffer.catalog() do name = nil end

This locks the system and forces you to stop the command (through the EXIT key on the front

panel). It does not delete the reading buffers from the instrument. This occurs because name is a

string type variable and not a reading buffer type.

Example

for name in dmm.buffer.catalog() do print(name) end

Print all user-created local reading

buffers in the system.

Assume the return is:

buf3

buf5

buf1

buf1 = nil

collectgarbage()

Deletes buf1.
