AN ON-LINE DEBUGGER FOR OS/360 ASSEMBLY LANGUAGE PROGRAMS
William H. Josephs · Defense Technical Information Center (DTIC) · 1969
The paper gives a description of DYDE, an on-line debugging program for use by assembly-language programmers on third-generation IBM computers. The ability to debug a program on-line can mean a significant reduction in the programmer's debugging effort. DYDE (Dynamic Debugger) provides the programmer with DDT-like capabilities of break-point insertion, modification of data and code, and symbolic-label references. It can operate under any option of OS/360, using only a small, user-written 'ping-pong' SVC and communicating with the programmer by means of the 1052 operator's console (employing WTO and WTOR) or, preferably, the 2260 graphics console (using the OS Graphics Access Method support).
