; These tests have two goals. To start with, we assume the worst and
|
||||||
|
; successively test the instructions needed to continue testing.
|
||||||
|
; Then we try to test all instructions which cannot be handled by
|
||||||
|
; zexlax - the crc-based instruction exerciser.
|
||||||
|
|
||||||
|
; Initially errors are 'reported' by jumping to 0. This should reboot
|
||||||
|
; cp/m, so if the program terminates without any output one of the
|
||||||
|
; early tests failed. Later errors are reported by outputting an
|
||||||
|
; address via the bdos conout routine. The address can be located in
|
||||||
|
; a listing of this program.
|
||||||
|
|
||||||
|
; If the program runs to completion it displays a suitable message.
