I am experiencing unexpected results with the functioning of the timeout variable as part of the SX/B "SerIn" command.  The following information is given in the help file.

[quote="SX/B Help File"]SERIN Pin, BaudMode, ByteVar {, Timeout, ToLabel} 

Timeout  is an optional byte or word variable/constant that tells SERIN how long to wait (in milliseconds) for incoming data. If data does not arrive in time, the program will jump to the address specified by ToLabel. [/QUOTE]

When I specify a timeout value of 10ms directly like this:
[CODE]serin SIn, T9600, Temp1, 10, SerialDataPaused[/CODE]
it seems to work as expected with a quick jump to SerialDataPaused when no serial data is received.

However, when I try to accomplish the same thing in this manner:
[CODE]tmpW1	Var	Word

tmpW1 = 10
serin SIn, T9600, Temp1, tmpW1, SerialDataPaused
[/CODE]
the jump to SerialDataPaused when no data is received does not occur for well over a minute! =O

It seems to me that both methods should produce nearly similar results.  What am I missing?  Have I overlooked something obvious in regard to the use of a variable?
