1.5.2.2 Configuring the Input to the package.
The programs in the package will expect to be able to interrogate the keyboard. Most
of the keys on the CPC464 keyboard return standard values except for the cursor keys.
It is possible to use the SETUP utility (see CP/M primer) to re-define the codes
produced by the keyboard, although, where possible, it is preferable for each different
package to be configured to accept the standard default values.
The column marked 'WP Value' in the table below indicates typical values which
might be set into the keyboard via the SETUP utility in a word processing environment
if, for example, cursor codes are required from both the cursor key cluster and a
portion of the keyboard, and the Word Processing package is only capable of
recognising one unique code for each operation.
The installation procedure for a package will normally consist of asking a number of
questions about the parameters of the CPC464 keyboard. The answers should be
derived from the table below, which is an extract from the Amstrad BASIC reference
