| 22 | <ul> |
| 23 | write-reg [-cpu <i>cpu_set</i>] |
| 24 | [-cwp <i>window-pointer</i>] [-gl <i>global-level</i>] [-tl <i>trap-level</i>] |

| 29 | <h4>DESCRIPTION</h4> |
| 30 | <ul> |
| 31 | Set a cpu register. If <a href="flag_cpu.html">-cpu</a> is omitted, |
| 32 | the current strand is used. |
| 33 | Use <a href="cmd_cpuregs.html">cpuregs</a> command to show the supported register names. |
| 34 | <p> |
| 35 | By default, the current cwp register, global level, and trap level are |
| 36 | used to access windowed registers, global registers, and trap |
| 37 | registers, respectively. |
| 38 | The -cwp, -gl, and -tl flags may be used to override these defaults. |
