Well, there's always DOS 'find'; it's a really dumb text search tool. 
But I suppose you want something more complex.  BTW, what's so difficult
about using 'grep'?  Basic syntax:

   grep "word" files...

For example:

   grep "hello" *.c

If you find this syntax difficult to understand, please tell us and
we'll try to help.  :-)

Okay, reading globbed filenames.  You may or may not be aware that in C,
the command line arguments to a program are passed in via the arguments
to main(), in the following form:

   int main( int argv, char *argc[] )

argv contains the count of arguments, argc is an array of strings
containing the arguments themselves.  When the command line is
processed, all globbed filenames are inserted into the argument list
just as if you'd typed them all out on the command line.  argv[0] is the
name of the program itself; argv[1] thru argv[argc-1] are the remainder
of the arguments.  Example:

/* args.c */
#include <stdio.h>
int main( int argc, char *argv[0] )
{
    int i;
    for ( i = 0; i < argc; i++ )
        printf( "argv[%d] = %s", i, argv[i] );
    return 0;
}

C:\CPROGS> gcc -o args.exe args.c
C:\CPROGS> ls
foo1.c	foo2.c	foo3.c	args.c	args.exe

C:\CPROGS> args foo*
argv[0] = c:/cprogs/args.exe
argv[1] = foo1.c
argv[2] = foo2.c
argv[3] = foo3.c

If that's not simple enough...

hth!
