Hi,
Can anybody explain
what is B37 Error? why it should occur? can u explain with an example
thanks in advance

IBM reference manuals are readily available online. Learn how to find them and use them.

Hello,

Suggest you start a collection of links to the IBM manuals you find you need. There will be quite a few. . . They are downloadable for free (which is handy when your internet connecton is down. . . I ride "bareback" and only have a collection of links for most IBM things.

The B37 is described in the "System Codes" manual (look at the section called System COmpletion Codes). It will also mention the IEC030I message id.

The IEC030I is described in the "System Messages" manual.

Just as an aside, the three digit system abend code format is (or maybe was) XCC where X is the return code from SVC CC. Most all system services are implemented via the SVC (Supervisor Call) instruction. The operand of the SVC is the number of the service. 37 may be space management, can't remember anymore and B is code 11 decimal return. So, a S107 may be a return code of 1 during a load/link/ or xctl svc (if that is what 07 svc actually is).

Hope this is somewhat instructive (even if I had to hedge on the actual SVC numbers).

SVC X'37' is end of volume, which is entered, for direct access data sets, when all currently allocated space for a dataset is used. Regular programmers rarely use it directly, though it is usually called by data management routines. SVC X'07' is XCTL only, a service that regular programmers rarely use.

The return code with the B37 will also give you more information. There can be complex issues here, so with out complete information you can not really get an answer.
