## Function

Remove whitespace from an ASCII text file

## Description

Removes all whitespace from the input sequence. trimspace replaces all white space with a single space.

## Usage

Here is a sample session with nospace

    % nospace
    Remove whitespace from an ASCII text file
    ASCII text file: seqspace.txt
    ASCII text output file [seqspace.nospace]:
