This caused the VM to read past the end of the buffer and write 56 words of junk into the emulator. 2019-04-09T01:40:05Z Jose Antonio Ortega Ruiz jao@gnu.org 2019-04-09T01:40:05Z urn:sha1:b72dc79eec3d369a38202522165f5ef4cfa5b98b Thanks to Kevin Brunelle There is a minor fix included with regards to tape devices. The test was failing if M == 0, when it should fail when M != 0. NOTICE: This patch changes the behavior of the VM and changes the function parameters for the ioc_ function. Documentation changes are included. Permits the following: LDX BLKNUM IOC 0(8) OUT ADDR(8) Write block from ADDR into disk[BLKNUM] IOC 0(8) IN ADDR(8) Read block from disk[BLKNUM] into ADDR ... BLKNUM CON 45000 Example possible block on disk I was having an issue writing a block to a drive and then reading back the same block. Because it is impossible to move the SEEK_CUR pointer backwards on a disk device, there was no way for a program to read back a block that it wrote to a disk without restarting or fiddling with ~/.mdk/disk?.dev files and symbolic links. I have added a function parameter to the ioc_ function and used it to pass the value of rX to ioc_. This permits us to use IOC commands to move the read/write head on a disk/drum device. I believe that this conforms to the potential meaning of Knuth's description of IOC for disk/drum devices. I have put in tests to verify that rX is positive and M = 0. I have updated the documentation to reflect this new behavior. This makes disks much more usable. Note: I won't be offended if this patch is rejected because it changed the behavior of the VM. I think it fits the spirit and enhances the functionality in a way that some might find useful. I wanted it for something I was working on, and I felt others might want the same. The thing with the paper-tape should be fixed, though. 2014-08-03T01:11:52Z jao jao@gnu.org 2014-08-03T01:11:52Z urn:sha1:45ada25e46d0dfd142c85d9f0ffe98998fb59c4e 2014-08-02T17:25:08Z jao jao@gnu.org 2014-08-02T17:25:08Z urn:sha1:42fb2b1e1100cb597dcdf41de73dae92279dd70e 2014-01-06T04:32:05Z Jose Antonio Ortega Ruiz jao@gnu.org 2014-01-06T04:32:05Z urn:sha1:fd6af75970ec60598c0bc3e1adcfcd2cb8b1da52 2014-01-06T03:51:23Z Jose Antonio Ortega Ruiz jao@gnu.org 2014-01-06T03:51:23Z urn:sha1:cfacca3047d62caa0a6b3f99fe1fbb0919130973 2009-10-11T17:54:34Z Jose Antonio Ortega Ruiz jao@gnu.org 2009-10-11T17:54:34Z urn:sha1:8c5835b547d8fe41d605db92b22644d4be7900a1 * mixgtk/gmixvm.c: inner_main_ signature corrected * mixutils/mixvm_loop.c: loop_ signature corrected * mixguile/mixguile.h: Cosmetics 2009-10-05T13:43:15Z Jose Antonio Ortega Ruiz jao@gnu.org 2009-10-05T13:43:15Z urn:sha1:66d60a12f13558a9a0e1a29212f8209844739827 2009-10-05T13:36:16Z Jose Antonio Ortega Ruiz jao@gnu.org 2009-10-05T13:36:16Z urn:sha1:201fabada08dea475113b2b91f28f44d020d355e 2009-10-05T08:31:37Z Jose Antonio Ortega Ruiz jao@gnu.org 2009-10-05T08:31:37Z urn:sha1:43cf2e905b1751db4464d6acb6e8e250cb691141
