Re: How to open another file and go to a search pattern

Sorry, when typing out text I have made some mistakes, which may have
given wrong impressions of what I tried at a couple of places. I should
have rather pasted the code I tried, but I had changed it by the time I
thought of writing a mail. Will correct it now.

Clarification: Tried exec search(searchpat)
It did not search in the current file. (My mistake in above mail.)

However the other thing that I tried was:
exec "/"searchpat
or more precisely, to avoid an extra space after "/"
exec join(["/",searchpat],"")

On either of these the message "Search hit bottom ...." appeared in the
current buffer itself. Only on hitting Enter the next file was opened.
From this I thought it is searching in current file.

Thanks for the tip. Will incorporate.

Precise command is:

exec "e " join(["+/",searchpat],"") file

This is opening the file, but to highlight the pattern I have to press
"/<Up>"<CR>. Looking for this last step to happen automatically.
