Hello!

I'm trying to figure out if it is possible to nest an "if" inside a "for" in the debugger?

This works:

for each i in m.var: print i: end for

Now I want something like this

for each i in m.var
    if i = "something"
        ? i
    end if
end for

So far no matter what I've tried I get back 

A block (such as FOR/NEXT or IF/ENDIF) was not terminated correctly. (compile error &hb5) in $LIVECOMPILE(256)

Tried these and more:

for each i in m.var : if i = "something" then ? i: end for

&

for each i in m.var : if i = "something" then ? i: end if : end for

&

for each i in m.var : if i = "something" : ? i : end if : end for

Anyone know how to do this, is it possible?

items = ["one","two","three"]
? type(items)
for each i in items
        if i <> ""
                ? i
        end if
end for

roArray
one
two
three

Is type(m.var) always "roArray" or "roAssociativeArray"?

I would have thought the last attempt would have worked, but in my own tests I see it doesn't

for each i in m.var : if i = "something" : ? i : end if : end for

So I dunno what can be done.

yeah, it won't work, since the parser makes assumptions - have to decide which form of `if` is used - and then it does not backtrack.

i think at some point i came with a very contrived way to accomplish something like the asked... except can't remember now. Ooops.

PS. Behold! I just devised you a new Rube Goldberg machine:

Brightscript Debugger> tbl = ["r", "a", "n", "d", "o", "m"]: for i = 0 to tbl.count()-1: ? {false:"", true: i.toStr() + chr(10)}[(tbl[i] > "m").toStr()]; : next
0
2
4

PPS. perhaps my old idea was

tbl = ["r", "a", "n", "d", "o", "m"]: for i = 0 to tbl.count()-1: while tbl[i] > "m": ? i: exit while: end while: next

Thanks for the reply, but now accomplish the same in the DEBUGGER.  I think Enterr got it, thanks guys!!
