// Text after a // will be ignored to the end of the line. The amount of white
// space between arguments isn't important, but new lines start a new command.

alias

alias str r? d? // labels register or device reference with name. When alias is applied to a device, it will effect what shows on the screws in the IC base. (housing)

alias vTemperature r0
alias dAutoHydro1 d0

move

d s // stores the value of s in d

move r0 42 # Store 42 in register 0

add

d s t // calculates s + t and stores the result in d

add r0 r1 1 # add 1 to r1 and store the result as r0
add r0 r0 1 # increment r0 by one

sub

d s t // calculates s - t and stores the result in d

mul

d s t // calculates s * t and stores the result in d

div

d s t // calculates s / t and stores the result in d

mod

d s t

// calculates s mod t and stores the result in d. Note this

// doesn't behave like the % operator - the result will be

// positive even if the either of the operands are negative

slt

d s t // stores 1 in d if s < t, 0 otherwise

sqrt

d s // calculates sqrt(s) and stores the result in d

round

d s // finds the rounded value of s and stores the result in d

trunc

d s // finds the truncated value of s and stores the result in d

ceil

d s // calculates the ceiling of s and stores the result in d

floor

d s // calculates the floor of s and stores the result in d

max

d s t // calculates the maximum of s and t and stores the result in d

min

d s t // calculates the minimum of s and t and stores the result in d

abs

d s // calculates the absolute value of s and stores the result in d

log

d s // calculates the natural logarithm of s and stores the result

// in d

exp

d s // calculates the exponential of s and stores the result in d

rand

d // selects a random number uniformly at random between 0 and 1

// inclusive and stores the result in d

// boolean arithmetic uses the C convention that 0 is false and any non-zero

// value is true.

and

d s t // stores 1 in d if both s and t have non-zero values,

// 0 otherwise

or

d s t // stores 1 in d if either s or t have non-zero values,

// 0 otherwise

xor

d s t // stores 1 in d if exactly one of s and t are non-zero,

// 0 otherwise

nor

d s t // stores 1 in d if both s and t equal zero, 0 otherwise

// Lines are numbered starting at zero

j

a // jumps to line a.

bltz

s a // jumps to line a if s < 0

blez

s a // jumps to line a if s <= 0

bgez

s a // jumps to line a if s >= 0

bgtz

s a // jumps to line a if s > 0

beq

s t a // jumps to line a if s == t

bne

s t a // jumps to line a if s != t

bdseal

d? a(r?|num) // Jump execution to line a and store current line number if device d? is set.

bdseal d0 32 #Store line number and jump to line 32 if d0 is assigned.
bdseal dThisVictim HarvestCrop #Store line in ra and jump to sub HarvestCrop if device dThisVictim is assigned.

yield

// ceases code execution for this power tick

#

// The following text will be ignored during compiling; use this to create comments.

---

This is a sample timer command set, alternating between 1 for 1 tick (0.5s), then off for 2 ticks (1s).

move r0 0		// Line 0: move the value 0 to register0
sub r1 r0 3		// Line 1: subtract 3 from the value in r0 and write it to r1
bltz r1 4		// Line 2: jump to line 4 if r1 < 0 (skip the next line)
move r0 0		// Line 3: move the value 0 to register0 
slt o r0 1		// Line 4: if r0 < 1 write 1 to the output, otherwise 0.
add r0 r0 1		// Line 5: increment r0 by 1
yield			// Line 6: wait until next power tick (0.5s)
j 1			// Line 7: jump back to line 1	

Example:

so you will do l r0 d0 SolarAngle
Sorry had last args swapped
That would read in the value
while,
s d1 Vertical r0
Would write the contents of r0 into the devices 1's Vertical property
additionally you can make some aliases
alias SolarSensor d0
l r0 SolarSensor SolarAngle

Another example:

Now the IC is inserted into the housing. The screws D0-D5 can be adjusted directly to the equipment (sensor, console, solar panel, etc.). The ports 'o' and 'i0-i2' have been removed. Instead, commands that directly read and write hardware parameters are added.
l <register> <data_channel> <parameter>
 reads the value of the parameter
s <data_channel> <parameter> <register_or_value>
 writes the value of the parameter
ls <register> <data_channel> <slot_number> <parameter> 
 reads the parameter value from the slot
For example, 
l r0 d0 Horizontal
 
s d5 Activate 1
 
ls r3 db 0 OccupantHash
