The FSC trace shows details of the processing of the file services subcommands APpend, PUt, Get, MGet, and MPut. This trace can generate very detailed information and therefore allows you to specify levels of detail for the trace points.
The level 1 tracing that is specified by entering FSC or FSC(1) is the level normally used unless more data is requested by TCP/IP service group. The level (n) can be a number from 1 to 8.
