OK. Katakanlah saya tidak butuh tampilan. Untuk masalah kalkulasi kan bisa si
programmer membuat bahwa kalau datanya nol (0) atau tidak diisi, maka user
wajib isi data itu, kalau tidak diisi, maka tidak bisa lanjut ke proses
berikutnya seperti proses save (simpan).
Kalau masalah error karena delete file, maka memang perlu trap error supaya
tidak timbul notifikasi (peringatan). Tapi kalau ketika input data, trap error
fungsinya apa ya ?Yang saya maksud trap error seperti syntax On error goto
labelPeringatan, atau trap error seperti on error goto 0. Kalau on error goto
0, ini memang bagus untuk programmer supaya tahu mana code yang salahnya. Tapi
kalau sudah diantisipasi semua kesalahan data dari input user, maka trap error
goto 0 sdh tidak berfungsi lagi. Menurut saya begitu. Lalu, trap error ketika
input data, fungsinya apa ya ? Apakah cuma karena mati lampu shg datanya error
atau bagaimana ?
Terima kasih atas jawabannya.

Hai Tio,
Setahu saya trap error diperlukan untuk tampilan maupun kalkulasi.

Maaf mau tanya.
Sebenarnya fungsi trap error untuk apa ya kegunaannya ? Kalau error terjadi
karena user tidak input data, kan programmer itu bisa buat semacam kewajiban
bagi user untuk input data....
Terima kasih atas jawabannya...
