[CM] csound score, 2 instruments

[Fergal Dowling]

Hi,
I wish to write a csound score for that uses two instruments, i1 and 
i2, and control their respective start times using independent time 
varying envelopes. To achieve this, I now output two separate .sco 
files, one for each instrument, and then copy and paste one into the 
other. How can I append the out the second files to the first?

Thanks in advance.
