How do I run a ABAQUS job which uses a user subroutine?

Using the following command : 

abaqus job=job-id user= < subroutine-filename >

For the Linux Teaching System Computers give the extension .f and for PCs give the extension .for. 
The user subroutine has to be in a separate file (say my_material.f). 
Example : abq681 j=plate user=my_material 
If there are more than 1 user subroutines then all the subroutines must be included in a single file. 
If using CAE then in the Job Create a Job and then click on the General tab and click on the browse button for user subroutine and choose the file containing the user subroutine and Click on OK in the browse window and also in the dialog box. Then submit the job.
