Extension of a flexible computer program for handling DNA sequence data

Our previously (Nucl. Acids Res. 10, 229 (1982] described program is largely extended. Maintaining the program architecture we are now able to present the same program with a highly increased comfort. The number of nucleotides per line is variable and the option for calculating restriction enzyme fragments is included. A four digit code guides through the program. The program is selfdefining and may be used without any prior computer experience. Copies are available on request.
