Thanks a lot... I've thought of a few things:
1. I need to maintain a table that contains the job id and the job name.
2. I cannot put a process that is running currently through my interpreter into the background, without first invoking the Stop (CTRL+Z) command.
3. Once I invoke the stop command, I can issue a command bg <process_name> to put the task into the background and then the interpreter will issue a signal to the process to resume itself.
4. If I have to bring a process into the foreground, I need to write code in my interpreter in such a way that it first stops the process and then brings it to the foreground and then resumes it (or get it directly?) and then ceases the command of the shell from the user (invoke a wait command until the process is complete?).
I am little confused about jobs and processes - the difference between them. I hope someone can clarify if my above steps seem ok and also the difference between a job and a process...

NAME
binfmtc-interpreter - binfmt_misc C handler
SYNOPSIS
binfmtc-interpreter C-source-file-name [command-line opions ...]
DESCRIPTION
binfmtc-interpreter compiles a C source file specified on the command-line using C compiler, and executes the resulting file.
It is designed to be used as a handler for binfmt_misc handler, which is a system used in Linux for handling arbitrary files as executa-
bles.
The command-line options are passed on to the compiled binary.
FILE MAGIC
There is a requirement for C source files to have the magic characters /*BINFMTC: at the beginning of the file.
That line also is used to specify the additional command-line options for C compiler.
ENVIRONMENT
GCC The compiler used. The default is to use gcc
CC The compiler used, if GCC variable is not set.
BINFMTCTMPDIR
Temporary directory used for binary and execution.
Falls back to $TMPDIR $TEMPDIR or /tmp
BINFMTC_DEBUG
enables debug output if set.
BINFMTC_GCC_OPTS
Additional GCC options. Use BINFMTC_DEBUG to verify the options being passed on to gcc.
The default is -O2 -Wall -g
