.code

start:

    call    main
    invoke  ExitProcess,0

main PROC USES esi

LOCAL pe32:PROCESSENTRY32
LOCAL hProcessSnap:DWORD

    lea     esi,pe32
    invoke  CreateToolhelp32Snapshot,TH32CS_SNAPPROCESS,0
    mov     hProcessSnap,eax

    mov     pe32.dwSize,SIZEOF PROCESSENTRY32
    invoke  Process32First,eax,esi

@@:
    invoke  printf,ADDR text1,ADDR PROCESSENTRY32.szExeFile[esi],\
            PROCESSENTRY32.th32ProcessID[esi],\
            PROCESSENTRY32.th32ParentProcessID[esi]

    invoke  Process32Next,hProcessSnap,esi
