It won't work unless you modify the UDF slightly.

Change the function declaration to:
 Code:
Function FTPput($Host, $Path, $File, $UID, $PWD, optional $FTPcmds1, optional $FTPcmds2)

Then change the commands to write the FTP command file, as such:
 Code:
; Create an FTP command file

If Open(1,$FTPchk+"\FTPcmds",5) = 0

	WriteLine(1,$UID+@CRLF)			
	WriteLine(1,$PWD+@CRLF)
	WriteLine(1,"binary"+@CRLF)
	WriteLine(1,"lcd "+$Path+@CRLF)

; Additional FTP commands passed to the function are actioned here
	WriteLine(1,""+$FTPcmds1+@CRLF)

; write the data put command
	WriteLine(1,"mput "+$File+@CRLF)

; Now get the transferred file back to a check area so we can confirm it worked
	WriteLine(1,"lcd "+$FTPchk+@CRLF)
	WriteLine(1,"mget "+$File+@CRLF)

; Additional FTP commands passed to the function are actioned here
	WriteLine(1,""+$FTPcmds2+@CRLF)

	WriteLine(1,"close"+@CRLF)		
	WriteLine(1,"quit"+@CRLF)

	Close(1)

EndIf

This is untested, but similar to things I've done in the past.

Realize that you now have two optional args - one to execute before the put and one to execute after. If you need to perform more than one command before or after, you'll need to build a string with the individual FTP commands separated by @CRLF - like "CMD1" + @CRLF + "CMD2..."
