Obtaining information about an OS/390 load module

You can use the ABTBQMOD program to obtain image type and virtual machine (VM) usage information for an existing Smalltalk load module. ABTBQMOD provides you with information as to how the specified load module was originally built. ABTBQMOD also supplies information about the image control table (ICT), which is setup by the system programmer for use with the ABTBMF1B JCL procedure. See your system programmer for more information about the ICT.

The ABTBQMOD program displays the following information about the image associated with the built load module:

The ABTBQMOD program also displays the following information about the Smalltalk virtual machine that will be used by the application image:

ABTBQURY is a JCL member in ABT.V4R5M0.SABTJLIB. To use the ABTBQMOD program, edit the JCL and supply the following:

For example, to obtain information about a Smalltalk application program named RUNMVS with ABTBQURY, submit JCL that contains the following statement:

QMOD RUNMVS

The following output is then displayed:

----------------------------------
Image Name          : RUNMVS
VM Module           : ABTBV140
Image Type          : Single Image
Execution Mode      : Static Link

To obtain information about the ICT with ABTBQURY, enter:

QMOD ICT

The following output is then displayed:

------------------------------------------
Smalltalk Image Control Table (ICT)   V420
------------------------------------------
ABTXICT Timestamp:  10/22/96 @ 12.34
1. DSN= ABT.TPO3.IMS.IMAGE
2. DSN= BJLLIB.NATIVE.SABTBIMG
3. DSN= ABT.NATIVE.SABTBIMG
4. DSN= BJLLIB.NATIVE.IMAGE
------------------------------------------

If the application could not be located, a message indicates that the load request failed.
