Princess Engine scripting

there's a "result" variable that's just an 8-bit number

"if" doesn't directly branch to anything, but if the condition is false then the next command is skipped
"if" statements can be stacked on each other, too:

@if> 5
@if< 10
@ifflag+ someflag
@ifflag- anotherflag
@goto wherever
"if the result is greater than 5 but less than 10, and if someflag is set but anotherflag isn't, goto wherever"

SYNTAX:
%whatever                              directly insert stuff inline into the compiled file, mostly for directives
bla bla bla                            bare text just directly displays onto the screen

@runasm                                start of an ASM section. A = result
clc
adc #1
@endasm                                end of an ASM section. result = A

CONDITIONS:
@ifflag+ FLAG                          if flag is set...
@ifflag- FLAG                          if flag is unset...
@if< value                             if the result is less than a value
@if> value                             if the result is greater than a value
@if= value                             if the result is equal to a specific value
@if<> value                            if the result is NOT a specific value
@ifyes                                 ask yes/no, then if the player answered yes...
@ifno                                  ask yes/no, then if the player answered no...
