Hi Charles, I'm just reading the docs and stumbled upon the following: Quote>>>>>>>>>> tib rb 1024 ; Text Input Buffer (1k) rb 2048 ; Stack (upper 2k) s0 rb 2048 ; Stack (lower 2k) d0 rb 40000h ; Dictionary (256k) h0 rb 80000h ; Code (512k) The memory footprint is basically the compiled image size, plus these values. It's a good idea to keep tib and s0 the same; <<<<<<<<<<<<Quote tib rb 1024 s0 rb 2048 "keep them the same"?? s. -- Stefan Schmiedl +-------------------------------+----------------------------------------+ |Approximity GmbH | EDV-Beratung Schmiedl | |http://www.approximity.com | Am Bräuweiher 4, 93499 Zandt, Germany | |mailto:stefan@xxxxxxxxxxxxxxx | Tel.
