I am having a csv file like:
sno pos code
1 2323 abc
1 2324 
1 2346 lss
. .    .
. .    .
. .    .
1 9999 hys
I have one more file like
sno start end
1 2320 2330
1 2350 2360
1 3556 3566
.  .   .
.  .   .
.  .   .
1  9990 10000
I want to print alphabets between these positions.
Desired output
1  2320 2330 abc
.    .      .
.    .      .
1  3560 3570 hgj
.    .      .
.    .      .
.    .      .
1 9990 10000 hys
Is there any way I can do this? My programming is very weak and need help for the same.
Thanks
