40 Neuron Assembler Errors (NAS)
NAS# Description
47 Offset must be a constant [NAS#47]

Constant is out of -1..-8 range [NAS#48]
Offset value is out of 0..255 range [NAS#49]
Offset value is out of 8..23 range [NAS#50]
First operand is out of 0..255 range [NAS#51]
Second operand is out of 0..255 range [NAS#52]
A constant, offset value or operand was outside the supported value range.
53 <f> is an unknown function name [NAS#53]
See the Neuron Assembly Language Reference for a list of supported
function names.
54 Invalid resource name [NAS#54]
A RESOURCE directive is being used incorrectly. RESOURCE directives
are reserved for use by the Neuron C Compiler. Do not specify RESOURCE
directives in your Neuron Assembly code.
55 Constant is too large [NAS#55]
56 Could use small branch instruction [NAS#56]
A performance warning. Smaller branch instructions use less code space
and execute faster.
57 Could use smaller 'PUSHS' instead [NAS#57]
You can use PUSHS to push immediate constants in the 0..7 range.
PUSHS uses less code space and executes faster than PUSH.
58 Useless instruction [NAS#58]
The instruction has no effect.

Could use smaller 'INC' instead [NAS#59]
Could use smaller ‘DEC’ instead [NAS#60]
Could combine ‘RET’ with previous instruction [NAS#61]
Could replace ‘CALLR’+’RET’ with ‘SBR’ [NAS#62]
Could replace ‘CALLR’+’RET’ with ‘BR’ [NAS#63]
Could replace ‘CALL’+’RET’ with ‘BRF’ [NAS#64]
Could replace ‘CALLF’+’RET’ with ‘BRF’ [NAS#65]
Could use immediate-operand instruction with previous push [NAS#66]
