Fold with an IF statement

[dantrader$]

Dear Forum,

I am attempting to code a fold loop with an if statement that increments the value of a variable if a condition is met. I am receiving highlighted errors that I cannot make go away, and would appreciate your thoughts and input. My code is the following:

def gup;
gup = fold m = 0 to 4 with bup=0 do If wup[m] > (.75*len[m]) then {bup = bup[1] + 1}; else {bup = bup[1];};

another version with some but fewer errors is:

def gup;
gup = fold m = 0 to 4 with bup=0 do If wup[m] > (.75*len[m]) then bup = bup[1] + 1 else bup = bup[1];

Any and all input on how to make this functional would be truly appreciated! I am looking forward to reading your creative solutions shortly.

you don't need, can't use , offsets on the temp variable within the fold.

within a fold loop, it is best to use getvalue()

try this

def gup = fold m = 0 to 4
with bup = 0
do bup + (If getvalue(wup, m) > (0.75*getvalue(len, m) ) then 1 else 0);
