I am note sure that IBM mainframe got syscalls.

But there are something. There is the standard C RTL. And
there are usually a pretty big chunk of extras. If it
does not have native *nix syscalls then it usually have
library emulating them.

I find it very difficult to imagine deciding to
use assembler to be able to read source files
and write either assembler code or object code.
