Queries About a Developer Exam Questions

Hi, I am about to take my developer exam again. I can remeber last time that there werer questions about the number of bytes that an integer "had" (it also asked about string types and decimal types if I remeber right). Does anyone here happen to know how many bytes each datatype occupies in memory?
Another thing I have seen is about the number of dataitems that you can have in a report, or dataport. Does anyone know these too?
Thanks a lot!
Matt.

1 byte = 8 bit = 1 char
Integer 32 bit = 4 bytes
String 1024 chars = 1024 bytesNavision developer0 -
Code of size N = N+1 bytes (I think)
Text of size N = N bytes
DateFormula = 32 bytes
Decimal = 12 bytes
Boolean = 4 bytes (actually it is an integer)
Integer = 4 bytes
Date = 4 bytes
Option = 4 bytes (actually it is an integer)
BLOB = 8 bytes + the size of the BLOB. (but I am not exactly sure about this one)
DateTime = 8 bytes
Time = 4 bytes
BigInteger = 8 bytes
Duration = 8 bytes
GUID = 16 bytes
TableFilter = 252 bytesRegards,Alain Krikilion

Code is N+2 bytes, and Text is N+1 byte.
Also note that sizes may be rounded up to 4-byte alignment for performance reasons in many cases.
See section "Choosing Data Types" in the "Table Fundamentals" chapter of the Application Designers Guide.0 -
Are you doing the Development 1 Intro to C/SIDE?
I'll look in my manual because they list all dataitems and how many bytes they hold. Just received the Development 1 Intro to C/SIDE manual cause I'll be writing my exam in the next 2 to 3 months.0
