2.  SB37 Abend

The most primary abend you will be getting is SB37.

//Spacejob Job Class=A,Msglevel=1,Msgclass=s
//Step1       Exec Pgm=SpacUtil
//Input        DD    Dsn=Sample.Space.Input,Disp=SHR
//Output     DD    Dsn=Sample.Space.Output,
//                       Disp=(New,Catlg,Delete),
//                       Dcb=(Lrecl=80,Blksize=800,Recfm=FB),
//                       Space=(Trk(500,100),Rlse)                                


If you are getting this SB37, then you need to increase the primary allocated space.
Follow the below steps to fix it.

Fix 1:
------
In the above Jcl, you need to change the 500 to, say, 800.

//                       Space=(Trk(800,100),Rlse)             

This will almost fix you SB37. If you are still getting SB37, follow Fix 2.

Fix 2:
------
If you are still getting SB37, then you need to increase the secondary allocated space. See the below line.

//                       Space=(Trk(800,500),Rlse)        

This will fix your job.

Fix 3:
------

If still you are getting the same SB37, then you need to change the Tracks to Cylinders. See below for the change.

//                       Space=(Cyl(10,10),Rlse)  

This will make your job fine.
