String Processing

I had a file with 150k records in it and I ran a tr on it to remove all new lines/CR which created one large record(whoops). Is there a way to add a \n after every 39th character without using 'dd' to turn it back into the original format? dd is way to slow. shell is ksh.

shell(1F)							   FMLI Commands							 shell(1F)

NAME

       shell - run a command using shell

SYNOPSIS

       shell command [command] ...

DESCRIPTION

       The  shell  function  concatenate  its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise
       /usr/bin/sh).

EXAMPLES

       Example 1: A sample output of shell command.

       Since the Form and Menu Language does not directly support background processing, the shell function can be used instead.

       `shell "build prog > /dev/null &"`

       If you want the user to continue to be able to interact with the application while the background job is running, the  output  of  an  exe-
       cutable	run  by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to
       save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing.

       shell can also be used to execute a command that has the same name as an FMLI built-in function.

NOTES

       The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local  environments
       will not be expanded by the shell because "local" means "local to the current process."
