Deleting rows based on True/False Criteria

[CatherineN]

I am attempting to delete entire rows if a certain column is false. This column has the following function:
=IF(MID(A1,35,3)="CMD",1,"")
So, if the cell (in column R) is "", I guess, I need the row deleted, and if it is 1, then I want to keep it. I am very lame with VBA and cannot find a command to delete an entire row, and the only example codes I'm finding are to delete blank rows. I have about 12 spread sheets, and each has about 65,000 entries (I would have liked it in 2 but it wouldn't fit, maybe once I delete everything I don't need), so I don't expect it to be fast, but I need some help. Would it be easier if I made the false something other than ""?

Thanks for the help

An easy way to do this is to ...

Add an additional column and fill it with sequential numbers (1,2,3 etc)
Sort by the column containing the blanks
Delete the section containing the rows with the blank columns
Re-sort by the column with the sequential numbers.
Delete the sequential numbers column

By macro you could do something like...

Set MyColumn to the column of interest. The ScreenUpdating commands are to speed the code up a bit by avoiding refreshing the screen each time.

Wow, you make me realize I was making it way harder than it was, trying to write scripts. All I had to do was sort by column R and then delete everything below the break between 1 and "".

Thanks for being the catalyst to that realization
