Jerry,

Apologies - honest mistake.

I did not realise that the discussion group done live on the internet
through Internet Explorer was linked to the discussion group I access
through Outlook Express.

summarised in a simple function !

I have two columns of data :
Soundings, Mass :
0.000 0.000
0.772 65.750
1.335 129.640
1.897 198.700
2.460 271.350
3.022 346.640
3.585 424.020
4.147 503.130
4.710 591.880
5.272 695.640
5.835 800.290
6.397 905.730
6.960 1011.760
7.522 1118.300
8.085 1133.090


the iterations of my known column of data, the soundings, is every 0.7 or
0.3.

I need to examine the data to increments of 0.1, and hence spread it out
over far more iterations.

Any good ways of doing this that you know of ?
