I was wondering if it was possible to slice two dimensions of a sequence in a
single statement. Example:
--begin code
include file.e
procedure testprint(sequence text)
for i=1 to length(text) do
puts(1,text[i])
end for
end procedure
sequence text1
text1 = {
"Hi there",
"Are you ",
"New to E",
"uphoria?"
}
procedure Main()
testprint(text1[1..3][3..7]) --the interpreter seems to end the
statement after the
end procedure --[1..3] in this line and it stops
--end code
Is there any way to do this in a single statement?
TIA,
CHARN

I don't think there is any way to do it with built-in commands, but you could
write a function:
function multiSlice(sequence s, sequence slices)
sequence t
integer l
l = length(slices)
s = s[slices[1][1]..slices[1][2]]
if l > 1 then
t = slices[2..l]
for i = 1 to length(s) do
s[i] = multiSlice(s[i],t)
end for
end if
return s
end function
