Fix Module CRC and Parity
Syntax
fixmod [] { []}
Function
fixmod verifies and updates module parity and module CRC (Cyclic
Redundancy Check). You can also use it to set the access permissions and
the group.user number of the owner of the module.
Use fixmod to update the CRC and parity of a module every time a
module is patched or modified in any way. OS-9 does not recognize a
module with an incorrect CRC.
You must have write access to the file before you can use fixmod .
