In addition to what sea and mjf have already noted, even if you do append the output of paste (rather than overwriting the output from paste) you still won't get what you want. The paste utility doesn't paste the input file onto the ends of lines it reads from the output file; it pastes lines from one or more input files to create lines in the output file.
You could run paste once for each each input file in turn to paste it at the ned of the appropriate output file into a temp file and move the temp file back to the appropriate output file. But running awk 100 times and running paste 100 times seems highly inefficient to me. I'd suggest something more like:
which runs awk once, paste once or twice, and chmod once or twice, and bash one extra time to run the commands produced by this awk script.
This code creates one or two temporary shell scripts to paste the appropriate input files together into your final output files, runs those scripts, and uses echo to remind you to remove those temporary shell scripts. If it does what you want; remove the echo in red in the awk script to actually remove the temporary scripts after that have been run.
If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk.

Hi!
I have a new problem with awk, this time I think is because I'm using it in bash and I don't know how to put the valor of the variable in awk. Here is the code:

a=$i
b=$

paste
paste(1) General Commands Manual paste(1)Name
paste - merge file data
Syntax
paste file1 file2...
paste -dlist file1 file2...
paste -s [-dlist] file1 file2...
Description
In the first two forms, concatenates corresponding lines of the given input files file1, file2, etc. It treats each file as a column or
columns of a table and pastes them together horizontally (parallel merging).
In the last form, the command combines subsequent lines of the input file (serial merging).
In all cases, lines are glued together with the tab character, or with characters from an optionally specified list. Output is to the
standard output, so it can be used as the start of a pipe, or as a filter, if - is used in place of a file name.
Options
- Used in place of any file name, to read a line from the standard input. (There is no prompting).
-dlist Replaces characters of all but last file with nontabs characters (default tab). One or more characters immediately following -d
replace the default tab as the line concatenation character. The list is used circularly, i. e. when exhausted, it is reused. In
parallel merging (i. e. no -s option), the lines from the last file are always terminated with a new-line character, not from the
list. The list may contain the special escape sequences:
(new-line), (tab), \ (backslash), and (empty string, not a null
character). Quoting may be necessary, if characters have special meaning to the shell (for example, to get one backslash, use
-d"\\" ).
Without this option, the new-line characters of each but the last file (or last line in case of the -s option) are replaced by a
tab character. This option allows replacing the tab character by one or more alternate characters (see below).
-s Merges subsequent lines rather than one from each input file. Use tab for concatenation, unless a list is specified with -d
option. Regardless of the list, the very last character of the file is forced to be a new-line.
Examples
ls | paste -d" " -
list directory in one column
ls | paste - - - -
list directory in four columns
paste -s -d"
" file
combine pairs of lines into lines
Diagnostics
line too long
Output lines are restricted to 511 characters.
too many files
Except for -s option, no more than 12 input files may be specified.
