+/**
+  @file
+  @brief Adds a user to a group on SASjs Server
+  @details Adds a user to a group based on userid and groupid.  Both user and
+  group must already exist.
+
+  Examples:
+
+      %ms_adduser2group(uid=1,gid=1)
+
+
+  @param [in] uid= (0) The User ID to be added
+  @param [in] gid= (0) The Group ID to contain the new user
+  @param [in] mdebug= (0) Set to 1 to enable DEBUG messages
+  @param [out] outds= (work.ms_adduser2group) This output dataset will contain
+    the new list of group members, eg:
+|DISPLAYNAME:$18.|USERNAME:$10.|ID:best.|
+|---|---|---|
+|`Super Admin `|`secretuser `|`1`|
+|`Sabir Hassan`|`sabir`|`2`|
+|`Mihajlo Medjedovic `|`mihajlo `|`3`|
+|`Ivor Townsend `|`ivor `|`4`|
+|`New User `|`newuser `|`5`|
