An integer variable type is supported under BASIC Plus. This format is similar to B (binary) variables except for the following:
• I variables come in only 1, 2 and 4 bytes
• I variables may hold negative values
• I variables use Alpha’s 68K byte order (high word – low word, low byte – high byte), instead of the strict low-byte to high-byte format used by B variables.
As far as A-Shell is concerned, there is no advantage to this variable type other than compatibility with programs already using it, except in cases where you need to support negative integers.
