The sane way to parse [19 02] control code arguments

gistfile1.py

def parse_19_02(source):
    str = []
    cur = next(source)
    while cur != 1 and cur != 2:
        str.append(cur)
        cur = next(source)
    str = ('String', str)
    if cur == 2:
        return ('19 02', [str], 'load "#a"')
    else:
        return ('19 02', [str, parse_long(source)], 'load "#a" -> $#bbbbbb')
