Assembling your program

If you assemble your program without using IBM® z/OS® Debugger Utilities, you must use the High Level Assembler (HLASM) and specify a SYSADATA DD statement and the ADATA option. This causes the assembler to create a SYSADATA file. The SYSADATA file is required to generate the debug information (the EQALANGX file) used by z/OS Debugger.

If you are using other Application Delivery Foundation for z/OS tools, see IBM Application Delivery Foundation for z/OS Common Components Customization Guide and User Guide to make sure you specify all the assembler options you need to create the files needed by all the Application Delivery Foundation for z/OS tools.
