A SAS program is comprised of one or more steps.

A DATA Step is a sequence of statements that can be debugged interactively
using the / DEBUG option.
See the online documentation for greater detail.

data NEW / debug;
  set sashelp.class;
  product1 = age * height;
  product2 = age * weight;
  product3 = height * weight;
run;

A PROC Step is a sequence of statements and options associated with a
specific procedure.  Generally you can not 'step through' a proc as it is
running.  The proc may have options for outputting diagnostic information to
the log or a table.

SAS macros generate text that is then passed to the active executor /
parser.  There is not a debugger for walking through a macros execution step
by step.  The generated text can be captured by using the MFILE and MPRINT
options.
