z/XDC Assembler Development Tool

z/XDC is a powerful, interactive tool for developing and testing Assembler, C/C++ and Metal C language programs in the z/OS operating system.

Using z/XDC, programmers can effectively find and correct errors in programs running in nearly any z/OS programming environment: authorized or nonauthorized, multitasking or single tasking, batch, TSO, or CICS, system exit or product exit, SVC routine or PC routine.

c/XDC
c/XDC expands z/XDC’s powerful, interactive source level debugging to include IBM's XL/C languages.

With c/XDC, programmers can move seamlessly between XL/C and Assembler code within the same program. You can STEP through your XL/C code as it executes, see statement operand values before and after statement execution, and display stack frames, variables, arrays and structures in real time. c/XDC functions equally well with all flavors of IBM's XL/C: C, C++, and Metal C in both 31-bit and 64-bit modes.
