In your original example the variable i was assigned the whole record (e.g. val1:env1:opt1). In the code that zaxxon suggested, the components val1 env1 opt1 were broken out and assigned to variables A, B and C. There would be no need to reference i, as there wasn't anything assigned to i anyway. You should be able to use A, B, and C as is.
From your original post, you also do a lot of extra work to only read a subset of lines from the input file. That isn't handled by zaxxon's example. Moving along the same lines as was offered, the following code will generate just the lines between START and STOP (inclusive) and assign them to the variables f1, f2, and f3 (A, B, C).
I'm trying to pass a filename, or all the files in the current directory to the ls command with a script. Unsuccessful so far, here are a few of my attempts:

ncflint
NCFLINT(1) General Commands Manual NCFLINT(1)NAME
ncflint - netCDF File Interpolator
SYNTAX
ncflint [-3] [-4] [-6] [-A] [-C] [-c] [-D dbg] [-d dim,[ min][,[ max]]] [-F] [-h] [-i var,val3][-L dfl_lvl][-l path] [-O] [-p path] [-R]
[-r] [-t thr_nbr] [-v var[,...]] [-w wgt[, wgt2]] [-X box] [-x] file1 file2 file3
DESCRIPTION
ncflint creates an output file that is a linear combination of the input files. This linear combination can be a weighted average, a nor-
malized weighted average, or an interpolation of the input files. Coordinate variables are not acted upon in any case, they are simply
copied from file_1.
There are two conceptually distinct methods of using ncflint. The first method is to specify the weight each input file is to have in the
output file. In this method, the value val3 of a variable in the output file file_3 is determined from its values val1 and val2 in the two
input files according to wgt1*val1+wgt2*val2
Here at least wgt1, and, optionally, wgt2, are specified on the command line with the -w (or --weight or --wgt_var ) switch. If only IR
wgt1 is specified then wgt2 is automatically computed as wgt2=1-wgt1. Note that weights larger than 1 are allowed. Thus it is possible to
specify wgt1=2 and wgt2=-3. One can use this functionality to multiply all the values in a given file by a constant.
The second method of using ncflint is to specify the interpolation option with -i (or with the --ntp or --interpolate long options). This
is really the inverse of the first method in the following sense. When the user specifies the weights directly, ncflint has no work to do
besides multiplying the input values by their respective weights and adding the results together to produce the output values. This
assumes it is the weights that are known a priori. In another class of cases it is the "arrival value" (i.e., val3 ) of a particular vari-
able var that is known a priori. In this case, the implied weights can always be inferred by examining the values of var in the input
files. This results in one equation in two unknowns, wgt1 and wgt2: val3=wgt1*val1+wgt2*val2.
Unique determination of the weights requires imposing the additional constraint of normalization on the weights: wgt1+wgt2=1. Thus, to use
the interpolation option, the user specifies var and val3 with the -i option. ncflint will compute wgt1 and wgt2, and use these weights on
all variables to generate the output file. Although var may have any number of dimensions in the input files, it must represent a single,
scalar value. Thus any dimensions associated with var must be "degenerate", i.e., of size one.
If neither -i nor -w is specified on the command line, ncflint defaults to weighting each input file equally in the output file. This is
equivalent to specifying -w0.5 or -w0.5,0.5. Attempting to specify both .BR -i and -w methods in the same command is an error.
ncflint is programmed not to interpolate variables of type NC_CHAR and NC_BYTE. This behavior is hardcoded.
