Debug Tool for z/OS

BUSINESS FLEXIBILITY:

The Debug Tool CICS Control (DTCN) Primary Menu screen is enhanced to support both a Load Module Name resource and a Compile Unit Name resource. The combination of a Load Module Name resource and a Compile Unit Name resource provides additional granularity, which helps in identifying the program you want to debug.

A RESTful HTTP access interface to read, create, update, and delete profiles in the DTCN profile repository is supported. A GUI interface allows you to manipulate the profiles from the workstation.

Debug Tool now supports debugging C and C++ programs that run in the Airline Control System (ALCS). This support is available only if you debug in remote debug mode.

The publication, The IBM Debug Tool Customization Guide now provides instructions for defining Terminal Interface Manager as an application under IBM Session Manager.

Currency support for IMS V11 and CICS TS V4.1 is provided.

IT SIMPLIFICATION:

Support is added for debugging of modules loaded from the Library Lookaside (LLA).

The CODEPAGE(ccsid) option is added to the XML option of the LIST CONTAINER and LIST STORAGE commands to improve the display of character strings on a 3270 that are encoded in alternate code pages.

The command SET MONITOR LIMIT is added so that the monitor window can display more that 1000 lines. QUERY MONITOR LIMIT will display the monitor limit setting.

Support is added for multiple concurrent updates of variable values in the monitor window.

A new command, POPUP, is provided to open a Command window to improve the ability to enter a long Debug Tool command. In addition, the Command window is automatically displayed when the user enters a command continuation character or starts a multiline command. A SET POPUP command is also included to control the size of the Command window.

A new command, FINDBP, is provided, which will help you easily find line, statement, and offset breakpoints in the Source object while in full-screen mode.

A new command, POSITION nnnn, is added to position to a line in the selected window.

A new CICS Screen Control Mode, which uses the new DTSC transaction to improve the control and management of debug sessions in an MRO environment, is provided.

Set and Query IgnoreLink for CICS in remote debug mode are supported.

Automatic saving and restoring of settings and breakpoints are now supported under IMS/TM.

The EQASET transaction can now be used to associate an IMS LTERM with a TSO user ID when the Debug Tool IMS Language Environment exit is used and the user has not signed on.

The ability to display a complex data item such as a group or a structure as a single character string is added in remote debug mode.

The LIST TITLED WSS command can now be used in the MONITOR command to place the variables defined in the Working Storage section of a COBOL program into the monitor window.

Display of COBOL DISPLAY messages in the debug console when in remote debug mode is supported.

Enterprise PL/I %INCLUDE files and C/C++ header files support is enhanced in remote debug mode.

Support is added for On Demand Load and Capture Source for C and C++ debug side files created with the DBGLD and CDADBGLD utilities shipped with the z/OS V1.11 XLC C/C++ compiler.

Support is included for an additional processing mode for STEP OVER in Assembler compile units for "calls" whose target is an internal routine within the same compile unit. This new mode is enabled by the SET ASSEMBLER STEPOVER EXTINT statement.

AT CHANGE monitoring of assembler variables with dynamically updated addresses such as those in a DSECT is added.

Support for the L (LIST) and M (MONITOR) prefix commands is extended to Assembler and Disassembly.

GOVERNANCE:

The EQASET transaction is enhanced to associate debug parms with LTERM ID if signon security is disabled and the user has not signed on.

Support is added to run in Browse Mode. In this mode, modifications to storage or registers and modifications to control flow (for example, using the GOTO or JUMPTO commands) are not allowed. Browse Mode allows debugging of a program but does not allow the user to change the behavior of the program. This may be desirable in a production environment to prevent unauthorized changes to the program behavior.

You can now show column 73-80 in a source view for a COBOL program.
