MI Map Basic

[Cognitor]

Dear Friends I need a help for the following. a) Suppose I have a map and within it I have a retangle with a physical dimension of 1 km per 2 km. Let's call two neighbor sides of this retangle as axis X and axis Y b) Suppose I have in the inner part of the retangle a movable point which can walk each 100 meters . c) Suppose that at a certain position of the point its distance to the four sides of the retangle are X1, X2, Y1and Y2 d) I want to do a routine that makes the internal point to "walk" to all positions inside the retangle and in each one it calculate the function Z= X1 + 2xX2 + 3xY1 + 4xY2   To do this I believe I have to program a routine in a program like MapBasic.   My questions are yhe following: 1) Is there another way to do what I am mentioning? 2) Is there another (free)  software like mapBasic that we can use to work with MaPInfo? 3) Where to buy the MapBasic?   I thank you in advance and please include me in the list for regular discussions Best Regards S�rgio Feitoza Costa Cognitor - Consultoria, Pesquisa Tecnol�gica e Treinamento Rua Baba�u, 103/202 - Rio de Janeiro - RJ - Brazil - CEP 21931-230 Tel 21 - 3934600 ou 9137 6257     Fax: 21 393 4600 E-mail : [EMAIL PROTECTED]         Home-Page: www.esquadro.com.br/~cognitor
