global

The global statement (command) declares one or more scalar or array global variables in the current package. It has the same syntax as the local statement. A scalar variable can be given an initial value by assignment using the form var = expr; see the examples that follow. If no initial value is given, the variable is initialized to null.

An array is declared by appending "[]" to the variable name. In this case the array can be a normal or an associative array, depending on context and will grow as necessary. A fixed size normal (that is, non-associative) array may be declared by specifying the size of the array inside the brackets, for example, arr[10]. The size may be an expression, which is evaluated at run time. The size is also the upper bound of the array since the first subscript is 1. To declare a fixed size array with a different minimum subscript, use the form

where lb and hb are expressions giving the low and high bounds of the array. Arbortext Editor will signal a run-time error if you attempt to access elements outside the bounds of a fixed-size array.
