President & Founder
David Cole – Architect, Lead Developer
- Level 3 Technical Support
- Assembler Coder
- Product Designer
Dave has owned and operated ColeSoft since 1988. He is the lead developer of the company's core product, the source level assembler debugger z/XDC, which first came to market as the "DeBugging Controller (DBC)" in 1980.
Dave has 40 years of programming experience in z/OS, MVS, and predecessor systems, and has earned a reputation as an authority in his field. ColeSoft serves as an informal clearing house for z/OS "lore", and z/XDC users often call upon Dave not to discuss z/XDC, but to ask about z/OS itself. Dave's understanding of z/OS internals has been greatly enhanced through his network of software engineers in z/XDC's user community, which has helped enhance the features of z/XDC and contribute to the dissemination of knowledge on z/OS internals.
