Index problem in while loop

[morak5]

Hi,

I have a vector j1 = [1 2 3, ..., 17] and a set of series labelled w_0, w_5, w_10, ..., w_80, and want to create a new series

jp1 = w_0*j1(1) + w_5*j1(2) + ... + w_80*j1(17)

The code below however, generates jp1 starting from !m=12 (!n=55), instead of !m=1. What am I doing wrong here? Thanks.

Code: Select all

scalar J= 17 ' Number of age groups between 0 to 80+ vector(J) j1 for !k = 1 to J j1(!k) = !k next series jp1 = 0 !m=0 while !m<17 !n = 5*!m !m = !m + 1 jp1 = w_{!n}*j1(!m) + jp1 wend

Your code is correct. What makes you think it isn't?

If you're looking at the modification history shown within the series, be aware that it's limited to six lines. It's therefore normal that you would only see a record of the last six assignments within your loop, corresponding to !m = 12 through !m = 17.

Ah, I see. Just checked the numbers and you are right. Many thanks, Matt, Gareth.
