.text:00401283                 mov     [esp+1Ch+var_1C], 1
.text:0040128A                 call    ds:__set_app_type
.text:00401290                 call    sub_401000
.text:00401290 start         endp
.text:00401290
.text:00401290 ; ---------------------------------------------------------------------------
.text:00401295                 align 10h
.text:004012A0                 sub     esp, 1Ch
.text:004012A3                 mov     dword ptr [esp], 2
