This command obtains a listing of all the messages in the current room

either "all", "old", or "new" to request all messages, only old messages, or
-new messages. Or it may be passed two parameters: "last" plus a number, in which
-case that many message pointers will be returned, or "first" plus a number, for
-the corresponding effect. If no parameters are specified, "all" is assumed.

+
+ Since this is somewhat complex, here are some examples:
+
+ Example 1: Read all new messages
+
+ Client: MSGS NEW
+ Server: 100 Message list...
+ 523218
+ 523293
+ 523295

+ 523190
+ 523211
+ 523218
+ 523293
+ 523295
+ 000
+
+ Example 3: Read all messages written by "IGnatius T Foobar"

MSG0 (read MeSsaGe, mode 0)
This is a command used to read the text of a message. "Mode 0" implies that
room= The name of the room the message originated in.
node= The short node name of the system this message originated on.
hnod= The long node name of the system this message originated on.
+ zaps= The id/node of a message which this one zaps (supersedes).
text Note that there is no "=" after the word "text". This string
signifies that the message text begins on the next line.
