8. Repeat the above steps until each block on the disk has been written once and read twice.
>>>set myd 0
>>>exer –bs 1 –bc a –l a –a 'w' –d1 'myd myd ~ =' foo
>>>clear myd
>>>hd foo –l a
00000000 ff 00 ff 00 ff 00 ff 00 ff 00 ...
Use an environment variable, myd, as a counter. Write 10 bytes of the pattern ff 00 ff 00 ... to
RAM disk file foo. A packet size of 10 bytes is used. Since the length specified is also 10 bytes,
then only one write occurs. Delete the environment variable, myd. The hd, hex dump of foo
shows the contents of foo after exer is run.
>>>set myd 0
>>>exer –bs 1 –bc a –l a –a 'w' –d1 'myd myd 1 + =' foo
>>>hd foo –l a
00000000 01 02 03 04 05 06 07 08 09 0a ...
Write a pattern of 01 02 03 ...0a to file foo.
