Considerable trouble with for loop in combination with awk

I have the text file where each line has the format:

chr10 101418889 101418904 0.816327

Right now the interval between column 2 and 3 is 15. I only want the two consecutive positions starting at position 1, write it to a file, then move up one position write to file etc. So that:

File 1: chr10 101418889 101418990 0.816327
File 2: chr10 101418890 101418991 0.816327
File 3: chr10 101418891 101418992 0.816327
and so on...

My code so far:
Code:
for ((i = 0; i <= 14; ++1)) do
awk -v h=$i '{$2 += h; $3 += h-14; print}' original_core_files/lung.core.low.5SitesMin.bed > ../core_motif_singleton_controls/script/$i.bed;
done

The output is a "0.bed" file and a stuck loop.

As you probably see my programming experience is very limited, thank you very much for any form of help!

Solved:
naturally I should have put i++ instead of ++1, is there a way to delete embarrassing threads like this one?

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
