Copying lines from one file to another file

I did a search before posting and couldn't find an example of what I need done. Anyway, I have a file called file1.txt, which has data like this:

Quote:
M977
57 62 78 94 96 107
M998
53 12 99 23 56 32
M1117
61 62 01 92 33 14
File2.txt contains:
Quote:
T55
12
M977
53 12
T90
01 88
M1117
33 14
So what I need to do is from file1.txt find the first line M977 in file2.txt and replace the line below it with the line from file1.txt. So file2.txt would look like this.

Quote:
T55
12
M977
57 62 78 94 96 107
T90
01 88
M1117
33 14
I would need to loop though file1.txt and continue though each line. The next pass would fine M998 in file2.txt and change the line below it with the line from file1.txt. Hope this makes sense.
