(Apologies for any typos.)

As a complete novice myself let us concentrate on your C executable.

Is your C executable on the your Governments Secrets List, or can you explain
EXACTLY what it does?

Can the whole be done via the default command structure of your particular shell?
If not, then is that what is your C executable is for.
(At this point a cannot imagine the shell command structure to be unable to do
anything that you want on the file extract given.)

If so, then attempt basic shell scripting first on a small subset of your database
to get a working model. It may perform like a _Sloth_ but by the time these guys
have figured out your problem from incorrect information your _Sloth_ script will
have done its job!

Now to the basics...
What is your machine, OS, shell, terminal etc?

These guys have made an assumption that your file is CSV, erm, meaning
COMMA separated variable(s), as far as I am aware.
Fair assumption to make when you quote it, then we see it has fields are separated
by pipes, let us call them PSVs. You HAVE to make assumptions that newlines and
MAYBE even carriage returns. (^M), exist and code for them too.

Why not convert your file to filename.CSV first as that is what you C executable
looks as though it requires and try again OR alter the C code to work on this PSV
format instead?

The professionals on here will give the results you want so long as you give them
the WHOLE information. These guys have been attempting ESP, (Extra Sensory
Perception), for years but sadly none of them have succeeded yet so give them
a fighting chance. If anyone can figure out stuff these guys can...

Even I, as a total novice, might be able to chip in but not as it stands with the
conflicting information you are giving.

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
