The process outlined involves multiple steps for assembling and verifying program code. It starts with parsing expressions and validating parameters to ensure the syntax and semantics are correct.

isValidParameter()

UrbanAssembler.java

ObjectGenerator.java

writeObjectFile()
generateEnd()
generateModifictations()
generateText
generateFormat() || directiveWord
generateLinkRecords
generateHeader()
findBasicInfo()
gets name && start

2. runPass1()

parseExpression()

SetUpLc()

shouldIncrement()

Newlc or Kicko

lc = param

tokenizeLines()
Else

Dont

If Syntax Valid

Line.java - tokenizeSource()

1. loadProgram()

last line
verifyEnd()
first line
verifyKicko()
verifyLine()
Read Line

parseProgram()

parseLine()

hasOperands() && syntaxValid()
parseNormalParameters()
