How to produce output in machine-easy-readable format, e.g. binary?

Andriy Zhugayevych

For large scale calculations (say 2000 basis functions) the standard Firefly-output requires a lot of time (comparable with Firefly run-time) to read eigenvectors, overlap matrix etc. when importing them into other programs, mainly because of keyword searching through large-size file, human-oriented formatting, text-field overflow checking. PUNCH file is more machine-friendly, but it does not contain e.g. overlap matrix. DICTNRY is not documented as far as I know. Datagam postprocessing capabilities are very limited. Is there a way to obtain eigenvalues, eigenvectors, overlap matrix in a compact format, e.g. binary or text similar to AUX-file in MOPAC (with the possibility to increase the output precision)?
