Hello,

I have a question, I want to store some data in two columns, for example

0001, stuff1 stuff2
0002, morestuff
0003, extrastuff
0004, more evenmore

As you can see column 1 is an ID and column 2 is one or more strings.

I want to do a search across another data set to say if column 1 (ID
number) matches in both sets and the contents of column 2 to data set B.

I initially thought to use a hash, but it scrambles the order of the
data so was unsure of its efficiency and use.

Any suggestions?

Many thanks
