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 Manual SOFT157:

Key Name	Value Hex	Value	[Key number if required	WP Value
		Decimal	to use SETUP utility]	(Decimal)
				(Decimal)
Cursor up	&F0	240	0	5
Cursor right	&F3	243	1	4
Cursor down	&Fl	241	2	24
Cursor left	&F2	242	8	19
C1r	&10	16	16	7
Return	&0D	13	18	13
Space	&20	32	47	32
Escape	&FC	252	66	27
Tab	&09	9	68	9
Del	&7F	127	79	127

1.5.3 Starting a Turnkey CP/M Package.

Normally all that is required is to type the package's main program name at the A> prompt. For example, to run a wages program called PAYROLL.COM simply type

PAYROLL
