3.7.3.3 AMSDOS

This program relinquishes control from CP/M and returns to the built-in AMSTRAD BASIC, from which the AMSDOS disc commands will be available.

3.7.4.1 FORMAT

The AMSTRAD DDI-1 disc system supports three disc formats, one of which has two variants.

The usual format is System format, obtained by using the standard FORMAT command. The system tracks are read from the disc containing the FORMAT.COM program and are automatically written to the destination disc.

The other formats are obtained by adding a single letter as a parameter to the command, separated by a single space:

For Data Format type: For IBM Format type: For Vendor Format type:

FORMAT D FORMAT I FORMAT V

**WARNING ** The licence agreement for your CP/M disc, (which is electronically serial number encoded) permits its use on a single computer system only. In particular this means that you are prohibited from giving any other person a disc with YOUR serial-numbered copy of CP/M on it. Because every system disc you make has your CP/M on it you must be careful, therefore, not to sell, exchange or in any other way part with, any system format disc. Instead you must format a disk in Vendor format, which is identical to System format except that the system tracks are blank, and then copy the relevant software onto that disc using FILECOPY or PIP. Be careful that the software you copy in this way is not itself copyright or subject to a licence agreement.

If you receive software on a disc in Vendor format, in order to use it conveniently you may either copy it to a system disc by using FILECOPY or PIP or alternatively convert the disc to a System disc by adding your CP/M to it. This is acheived with the BOOTGEN and SYSGEN commands.
