Hi,
the problem seems to be that you let APL print to a terminal (which wraps
long lines at ⎕PW).
A better way is probably to use one of the ⎕FIO functions in your
APL script as to write directly to the output file (which bypasses
the terminal).
Of course output forwarding in the shell would

One thing you could do is to increase the print width ⎕PW so that it
doesn't wrap, but ultimately this default printout is intended for
human consumption.
If you change your printing width APL may not print the overflow of each
line as a separate line.
tmp←2 50 ⍴ ⍳ 100
⎕pw←225
tmp

Try adding the option "--PW 1000" (or any large number less than
1). That will set the print width to huge.
The tr utility with the -s option can compress repeated spaces into a
single space.
sed '$d' will kill the last line.
So something like
apl --PW 500 --eval "2 70⍴⍳140" | tr
