R or RA - run (i.e., resume execution)

Usage:

r [<address]
ra [<address>]

Examples:

<carriage return>   (same as typing r)
r
r 1275
ra 2376

Description:

This command may be used to resume execution of the target program. Unless the trace mechanism has been previously engaged, the trace package will lose control until either a breakpoint is executed, or a TSX1 (or XED) TRACE invokes the package again. If execution is being resumed from a serviced breakpoint, the original instruction at the breakpoint location will be executed at this time (provided a run address, A1, is not specified).
