Concatenating Hundreds (!) of signals

I have over 300 short duration events of one channel imported from Dewesoft. Each is stored in a separate folder called Data’i’.

I have copied the first signal as a base and wish to concatenate the remaining on to it (not too worried about gaps in time, so intend to use ‘:’).

I think the way to do this is using a “for” loop, something like:

for i=2 to 300
‘Base:’dataisignal0’
end

How do I combine strings and numbers in order to execute this concatenation?
