+.II echo
+The command
+.B prompt
+echoes a string onto the standard output.
+It resembles the COHERENT command
+.BR echo ,
+but it does not write a newline character after the echoed string.
+Thus, you can use
+.B prompt
+to write a prompt onto the screen.
+.SH Example
+The command
+.DM
+	prompt "Please enter your name: "
+.DE
+.PP
+writes the following on the standard output:
+.DM
+	Please enter your name: _
+.DE
+.PP
+The underscore character marks where this command leaves the cursor.

+COHERENT Lexicon:
+.B
+echo

+.SH Notes
+.B prompt
+looks for an environmental variable called
+.BR ECHONOCR .
+If the variable is missing or not equal to
+.BR \-n ,
+then
+.B prompt
+calles the COHERENT command
+.B echo
+with its \fB\-n\fR option, which drops the newline.
+If
+.B ECHONOCR
+is set to anything other than
+.BR \-n ,
+then
+.B prompt
+calls
+.BR \ec
+option, which is used by some UNIX systems.
+When using
+.BR /rdb
+under the COHERENT system, it is best just to not set
+.BR ECHONOCR .
