+ The aim of the program was to show the possibility  to reuse\r
+ the procedure Traverse twice in two different environments: \r
+ Stacks and Queues.\r
+\r
+ Traverse+Stacks => Depth First Search \r
+ Traverse+Queues => Breadth First Search\r
+\r
+ The restriction imposed was:\r
+                   TO NOT DUPLICATE THE TEXT OF TRAVERSE!\r

+ Type Menu is implemented as a coroutine which have as attributes\r
+       (a) the list of possible options and\r
+       (b) a sub_menu\r
+ This imply that the different menus form an arbre; \r
+ It is fixed, in this implementation, that the first option is always \r
+ a step to the previous menu. \r
+ Menu was generated in the main program; The structure of it is as follows:\r
+\r
+\r
+                      main menu\r
+\r
+                 /           !\r
+             graph        algorithms               help\r
+              /                                    /  !   )\r
+  clear  import  modify  create                next  prev  reset  \r

+ Before executing the program make sure that an appropriate \r
+ driver was selected. \r
+ In order to do so execute a batch file\r
+        exec\r
+ (Do not forget to leave Norton Commander!)\r
+ The ecran dimention is 640x480.\r
+\r
+ The auxiliary files \r
+                       graf.txt\r
+                       graf.dta\r
+                       graf1.dta etc\r
+ are supposed to be in c:/loglan95/   \r
+ This can be obiously changed bz programer (in the text of the program).\r
+     \r
+ The  is supposed to be QWERTZ.\r
