Fix Module CRC and Parity

Syntax

fixmod [<opts>] {<modname> [<opts>]}

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.

Use the -up=<hex perm> option to set the module access permissions.

You must specify

<hex perm> in hexadecimal. You must be the owner of

the module or a super user to set the access permissions. The permission

field of the module header is divided into four sections from right to left:

owner permissions

group permissions

public permissions

reserved for future use
