Loading debug data from multiple CSECTs in a single assembly using separate LDD commands

If SET LDD SINGLE is in effect, follow the process described in this section.

When you enter the command LDD MYPROG, z/OS® Debugger finds and loads the debug information for both MYPROG and MYPROGA. However, because you specified only MYPROG on the LDD command and SET LDD SINGLE is in effect, z/OS Debugger uses only the debug information for MYPROG. Then, if you enter the command LDD MYPROGA, z/OS Debugger does the following steps:

1. If you entered a SET SOURCE command before entering the LDD MYPROG command, z/OS Debugger loads the debug data from the data set that you specified with the SET SOURCE command.
2. If you did not enter the SET SOURCE command or if z/OS Debugger did not find debug information in step 1, z/OS Debugger searches through all previously loaded debug information. If z/OS Debugger finds a name and CSECT length that matches the name and CSECT length of MYPROGA, z/OS Debugger uses this debug information.
