[ncl-talk] VB: write_table problem

[Wei Huang]

Elin,

First, it is better to use write_matrix, rather than write_table, as the
later is more for a mixed type of data.
http://www.ncl.ucar.edu/Document/Functions/Built-in/write_matrix.shtml

Secondly, the index in your list create is wrong, you'd better use:
ListPush(dlist45,(/tslice45(j,:)/))

Then your loop index could be wrong as well, but could not see from this
short script snap.

Regards,

Wei
