creating a dummy variable based on a list of elements

hi,

suppose that I have the folllowing table:

text
The banks and financial companies
The bankers association
First bank of England
financial banking institutions

If either the element "banks" or "financial" is present in an entry, then the new dummy variable =1, else 0.

So the table should be like this:

textHeader 2
The banks and financial companies1
The bankers association0
First bank of England0
financial banking institutions1

thank you!

Re: creating a dummy variable based on a list of elements

thanks Xia, your posts are very helpful, (as well as the posts of the other users)!

I actually tried to do this myself and even experimented with prxmatch, but even the smallest syntax inaccuracy can make the whole code not work (or work in an unintended way ...)

Thanks again!
