Thanks for your patience! After making the correction that you 
recommended (eliminating the space between -> and STR ), the program 
appears to function as expected.  After executing, I have the value: 
1 in the x-register. 
I believe that the value: 1 is the code that XMIT
returns if the transmission was successful. 
So from here the likely head-scratcher will be how to get the PC and 
the target PC application to receive the string.
BTW, your knowledge of RPL and the 4x:50 family are impressive!
