Layer 117 was not listed in eagle.

Some content has been added in Layer 117.I tried to open that in lower version in another PC. But I couldn’t find Layer 117.This was not listed when I click the display botton…Anyone tell me how to view that.? Thanks…

On the command line enter:

layer 117 a_name_for_this_layer

then it will show up in the listed layers. This information is available by entering HELP LAYER in the command line.
