The limit appears to be 255. Try this code:
include get.e
procedure make_file( atom params )
integer fn, line
fn = open("params.exw","w")
puts(fn,"without warning\nprocedure test(")
line = 0
for i = 1 to params do
printf(fn," atom a%d",i)
line += 1
if i != params then
puts(fn,",")
if line = 5 then
puts(fn,"\n")
line = 0
end if
end if
end for
printf(fn,")\n\t--? %d\nend
procedure\ncall_proc(routine_id(\"test\"),repeat(0,%d))\n",{params,params})
close(fn)
end procedure
atom params, done
params = 0
done = 0
while not done do
params += 1
make_file( params )
done = system_exec( "exw params.exw",0)
end while
printf(1,"Failed with %d parameters\n\nDone\n",params)
if wait_key() then end if
