I have a list of files, 4 files for example
Then I have two buffers ifa and ifb giving me the file numbers
from which I need to get a group of data. For example, the first
four groups use file 1. The fifth group uses data from file 1 and
file 2.
I am thinking of storing all the data in the file to a buffer called
blk. So I just open the file, read each record and put it in blk.
So for groups 1 to 5, I get the group data from blk. For the fifth group
I also need to get the data from file 2. Thus I am thinking of having
two blocks, blka and blkb that store two files.
I have put something in fortran, however c will do. I would be grateful to get some help constructing the code to do this.
fls(4) = [fname1,fname2,fname3,fname4]
ifla(1:ngrps) = [1,1,1,1,1,2,2,3,3,3,4,4]
iflb(1:ngrps) = [1,1,1,1,2,2,2,3,3,4,4,4]
do igrp = 1, ngrps
open file ifla(igrp)
do irec = 1, nrec
read file(ifla(igrp)) rec(irec)
store in blk
enddo
fill group from blk
enddo
