However, it is extremely inefficient (it may fall into an infinite loop). When I do not use %o!wks.maxrows for loop, the situation can not be improved. What's a problem? %o="data1"; %p="_b"; time=5; spts=3*6*60; win -t D; %w=%h; loop(ii,time*6*60+1,%o!wks.maxrows) { bigini=ii-time*6*60; endi=ii-1; curve.data$=%o%p; curve.result$=%w%p; curve.i1=$(bigini); curve.i2=$(endi); curve.smoothpts=$(spts); curve.adjave(); %(%o,3,ii)=%(%w,2,%w!wks.maxrows); clearworksheet %w; }; win -cd %w; eno [/quote]   Check here to include your profile signature.
