+<h2>Set commands</h2>
+
+Set commands can be used to set value of memory cells, bits, or port
+pins. Those commands that set value of memory interpret their command
+lines a litle bit different than other commands. First parameter is
+always the start address of the memory area which is being set. This
+parameter is followed by a list of data parameters. Data can be
+specified by a number. Numbers must begin with a digit. Each number
+specifies one byte of data. If the parameter begins with a non-digit
+character, it is interpreted as string of characters and this kind of
+parameter specifies as many bytes as many characters the string
+has. Strings can contain escape sequencies (see description of <a
+href="cmd_general.html#wi"><b>wi</b></a> command where escape
+sequencies are discussed) but they can not contain spaces because
+space characters (space, tabulator and vertical tabulator) separates
+parameters. Spaces can be specified as escape sequences or separated
+number parameters if needed. Only space characters separate data
+parameters while normaly comma (<tt>,</tt>) and semicolon (<tt>;</tt>)
+are interpreted as separator characters too.
+
+<a name="si"><h3>si addr data...</h3></a>
+
+Write data into internal RAM area. First parameter specifies start
+address of memory area to set and other parameters are data to set.

+Result of the command is a memory dump of area which has been modified
+by the command. If there is syntax error in a data parameter then
+remaining parameters are dropped out.

+
+This command is similar to <a href="#si"><b>si</b></a> command
+described above but it is used to modify external RAM.
+
+
+<a name="sc"><h3>sc addr data...</h3></a>
+
+This command is similar to <a href="#si"><b>si</b></a> command
+described above but it is used to modify code memory area (ROM).
+
+
+<a name="ss"><h3>ss addr data...</h3></a>
+
+This command is similar to <a href="#si"><b>si</b></a> command
+described above but it is used to modify SFR. Other difference is that
+first parameter (<b>start</b> address) can be specified by name of SFR
+not by address only.

+Modify bit(s). First parameter is address of first bit to modify. See
+description of <a href="#db"><b>db</b></a> command how bit address can
+be specified. If first character of data parameter is <tt>0</tt> it
+means <i>zero</i> otherwise it means <i>one</i>.

+
+This command can be used to sep up output values of external circuits
+connected to port pins. If a port bit is used as output to drive
+external circuits, do not set corresponding pin bit to zero because
+read back value of the port can be false. First parameter must be
+number of the port between 0 and 3.
