HI,

Gnat 3.13 on win98 and linux.

I am creating a menu and I am grabbing the terminal input using
get_line, but on this particular command the last 1 .. 3 characters
can be numerals in the range of 1 .. 999.

I am considering character'pos but how can I manipulate to an integer?

Extracted from menu:

The commands work as I require them including error handling.
If I dont use get_line I can get the integers but I cant resolve the
error handling.

 elsif Input(1..4) = Link and  19 < Max_Size and Max_Size < 23 then
         Nodea := Input(6..11); Nodeb := Input(13..18);
         Edget := Input(20..22);
         Put("The command is : "); Put(Input(1..4)); New_Line;
         Put("Node A is : "); Put(Nodea); New_Line;
         Put("Node B is : "); Put(Nodeb); New_Line;
         Put("Cost is : ");   Put(Edget); New_Line;

         Int_Range := Max_Size - 19;
         Put("Cost range is : "); Put(Int_Range); New_Line;


I now want to get the last three characters and convert them to
integers
