Unix c-shell - replacing/incrementing values in columns?

2 21
1 12
3 123
4 1234
6 49
0 49
33 212

I need to replace/increment all the values in the 2nd column that correspond to 0 in the first column.

so for
0 49
i would get
0 50

this can be done through:
paste num4.txt num.txt | grep ^0 | dm x1 x2+1

the most important thing is to preserve this increment in the file which the above command fails to do.

basically i need the completed file looking something like this:
2 21
1 12
3 123
4 1234
6 49
0 50
33 212

what would be the most effective way to go about it...?

thanks!
