Variable types

A variable is a reserved space of memory to allocate a value, and this space is defined by types.

First we must define a bit, one bit is a binary value that can be 0 or 1, two logical values.

Types:
ExtNameRangeMemory consumption
.bByte-128 to +127is really 8 Bits
.wWord-32768 to +32767is really 2 Bytes
.lLong-2147483648 to +2147483647is really 4 Bytes
.fFloatUnlimitedspecial format to allocate floats numbers, 4 Bytes
.sStringString lenght + 1is really 4 Bytes, that contain the address where the string is allocated
