Indicator Variables
The syntax for referring to an indicator variable is the same as for a simple variable, except that an indicator variable is always associated with a host variable:
host_variable:indicator_variable
Syntax Note:
The indicator variable can be a simple variable, an array element or a record component that yields a 2-byte integer. The type indicator has already been declared by the preprocessor. For example:
## var
## ind_var, ind_arr[5] : Indicator;
var_1:ind_var
var_2:ind_arr[2]
