at keyword

You can use the keyword “at” to make an alias to a variable, for example, you can write a library without using register 

names, and later in the main program to define those registers, for example:

module MyModule

dim PORTAlias as byte external ‘ here in the library we can use its symbolic name

program MyProgram

dim PORTAlias byte as at PORTB ‘ this is where PORTAlias is fully defined

Note: Bear in mind that when using 

at

 operator in your code over a variable defined through a 

external

 modifier, 

appropriate memory specifer must be appended also. 

bit type

The mikroBasic PRO for dsPIC30/33 and PIC24 compiler provides a 

bit

 data type that may be used for variable 

declarations. It can not be used for argument lists, and function-return values.

dim bf as bit  ‘ bit variable

There are no pointers to bit variables:

dim ptr as ^bit     ‘ invalid

An array of type bit is not valid:

dim arr as array[5] of bit     ‘ invalid 

Note: 

- Bit variables can not be initialized. 

- Bit variables can not be members of structures and unions. 

- Bit variables do not have addresses, therefore unary operator 

@

 (address of) is not applicable to these variables.
