you can combine the strings with something that is unique for the strings

for ex.
Outgoing(1)="Hi"
Outgoing(2)="I"
Outgoing(3)="am"
Outgoing(4)="John"
Outgoing(5)="!!!"

for i=1 to Ubound(Outgoing) Step 1
strOut=strOut+Outgoing(i)
next i

you can combine the elements with a "|" sign(Chr(127))

than you can separated them with | as the delimiter
