Variables in GaspardOS LANG

All variables are stored outside procedures.

The only exceptions are procedure arguments.

Declaration is simple and direct:

Example

global uint64_t x = 33;

global uint32_t x_32bits = cast uint32_t 33; // the cast operator is used because every integer in my language is 64-bit by default

global double db = 4.677; // doubles are supported without any trouble; they are not my main concern at the moment...

// ----- note: STRING AND WSTRING

global string message_gaspard = " agent.... \n"; // ASCII string type: ptr uint8_t

global wstring message_gaspard_unicode = L"WSTRING ééééé@@àààà \n"; // wstring ptr uint16_t or uint32_t, depending on the platform

A procedure can, of course, change the value of a variable.

A variable does not have to be assigned a value.

For example:

global double db; // no problem
global ptr uint64_t compteur2; // for a ptr (pointer), this makes perfect sense: the address will be determined in the procedure

Warning

It is not perfect!
