Thanks for answer
but I not have complaint with the manual
is only a future suggestion.
For a beginer If try to write any of the codes of the manual

The manual of the AMSTRAD come with every command and with
a source code can run by sample. And explain every process very clean inclusive for one never program. And if true not other manual I see are how that.

The new manual of GStudio are better than before. But think only need code samples for make perfect
