In short, your best bet is probably to re-write the entire file. Read a
line from one file, substitute text as necessary, rewrite line to new
file, repeat ad lib.

Note also that this:

>       gets( filename );

is an evil function, which you shouldn't use under any circumstances
excepting physical duress above the "agony" level, and that this:

>    while ( !feof( fileptr ) )
>    {
>       fgets( strline, MAXLINELEN, fileptr );

is not the best way to read a file, because:
