Echelon Neuron - Manual (Page 179)

Example:
This example determines if d’10 >= d’20.
push #d’20 ; (d’20)
push #d’10 ; (d’10, d’20)
call _gequ8 ; (0)
_gequ8s (Greater Than or Equal Signed, 8 Bit)
This function returns a >= b, where a and b are signed.
Stack Transformation: (a, b -- a>=b)
Location: Near
Registers Affected: None
Example:
This example determines if d’10 >= -d’10.
push #@lb(-d’10) ; (-d’10)
push #d’10 ; (d’10, -d’10)
call _gequ8s ; (1)
_get_sp (Get Stack Pointer)
This function gets the address of an item on the stack. -1 specifies the address of
TOS, -2 specifies the address of NEXT, and so on. Note that because TOS is
implemented as a dedicated special CPU register, you cannot accessed it through
a pointer calculated with _get_sp.
Stack Transformation: (offset -- address(2))
Location: Near
Registers Affected: None
Example:
This example gets the address of stack item c.
push #@lb(-d’3) ; (-3, a, b, c)
call _get_sp ; (&c(2), a, b, c)
_inc16 (Increment, 16 Bit)
This function increments a 16-bit value by 1.
Stack Transformation: (value(2) -- value(2)+1)
Location: Near
