I worked with ACP/TPF in the distant past. All programs were written in S/370 macro assembler. My department tested C, but it was dismissed as too slow, generating code that was too inefficient. But if you are maintaining this software now, you're definitely not poor. Also, I probably wouldn't mind doing that now, it certainly wasn't the worst code I ever encountered, by far.
