Some valuable information to know if trying to update your own CONFIG.INI.  Note that this is only for updating the display and how the command is compiled and decompiled, and does not actually change what a command does:

Format is:

[CD]
name=
strc=
lngt=

[CD] = Hex ID of the Command you're editing/updating.

name= = Name displayed for the command, such as NewCommand.  Brackets () are concatenated on their own, so don't include them.  This causes the command to be displayed as the given name instead of its Hex ID when you decompile the event, so instead of something like {CD}(), we'd see NewCommand()

strc= Format for each field in the Command.
b: Byte in Hex
w: Half-Word in Hex
e: Unsigned Half-Word
r: Signed Half-Word
n: Unsigned Byte
m: Signed Byte
For example, bbb means the Command accepts 3 Bytes worth of input in the form of NewCommand(xB1,xB2,xB3).

lngt= = Length of the Command in Bytes, including the Command ID.  Following our example, the lngt of our command would be 4: 1 for the Command ID, +1 for each Byte of input.
