It helps to look at what the person is trying to do before making a suggestion.

The line CALL FDNET.BAT TRY in a BAT file will execute ("call") the
second FDNET.BAT file, and FDNET.BAT gets the single argument TRY.  If
you look at FDNET.BAT, you will see these lines at around line 65:

││if /I "%1" == "TRY" goto Start
││if "%1" == "" goto Start
││goto %1
││goto End

And at around line 85, you have these lines:

││:Start
││vecho /t %_FDNET.LANG% INTRO
││REM if custom Packet Driver batch exists then don't test and just use it!
││if exist FDNETPD.BAT goto CustomPD
││
││if /I "%1" == "TRY" goto TryAnyway
││REM Detect Virtual Machine Platform
[..]



So CALL FDNET.BAT START and CALL FDNET.BAT TRY are similar, but with
TRY the FDNET.BAT will also attempt to load some other stuff (which
happens at FDNET.BAT line 158).
