Hello man vector gives Code: NAME vector - Vector data type for Tcl SYNOPSIS vector create vecName ?vecName...? ?switches? This I saw somewhere has been used in C code as follows cellWidth = vector(1, numNodes); cellHeight = vector(1, numNodes); I wanted to know, how can this vector can be used. Because when I tried to use it, it said be vector not declared, is ther some particular way to use TCL object. As it is C code, so i m sure it is not at all related to vector class can some one shed some light if this is vector what I am thinking of, because I didn't found any vector defination in any other file, where I saw this use of vector. I am Feisty Fawn (7.04)(Ubuntu Linux) and use gcc. -Thank You
