Simple-SIC-Assembler

It is simple sic assembler to get the assembly code and generate the object code.
When it is executed, you enter a file called temp and it comes out as follows.

Input(temp file)

test start 1000
first lda zero
sta len
lda zero
sta result
jsub strlen
jsub strcpy
jsub strcmp
lda result
j end
strlen ldx len

sta len
j strlen
back rsub
strcpy ldx zero
cloop ldch str2
stch str1

jlt cloop
rsub
strcmp ldx zero
cploop ldch str2
comp str3
jlt small
jgt big

j cend
big lda plus
sta result
j cend

jlt cploop
cend rsub
zero word 0
one word 1
minus word -1
plus word 1
len resw 1
result resw 1
str1 resb 10
str2 byte c'test string'
null word 0
str3 byte c'test string'
end end first
