STEP -- Causes DEBUG to execute the next statement in the target program and
then halt the target program. A combination of GO and BREAKPOINT
commands is usually best for advancing a program past many statements,
and a STEP command is usually best for advancing a program past one
statement. ST is the legal abbreviation for STEP.
> STEP (Execute the next statement, then halt.)
> STEP -Over (Suppress single-stepping through a routine about to be
called. For example, suppose the program is currently
stopped at a statement that calls a routine. If you
specify STEP, DEBUG single-steps into the routine. If
you specify STEP -Over, DEBUG runs throught the routine
at full speed.
> STEP -Until 25 (Single-step from the current location until statement 25.
Single-stepping causes your program to run VERY slowly.)
