Issue with Sizeof() and may be other...

[Psychophanta]

Next tip shows it , because it is easy to see the failure in the returned values:

Code: Select all

character.q
Debug SizeOf(character); displays 2

character2.q
Debug SizeOf(character2); displays 8

ascii.f
Debug SizeOf(ascii); displays 1

ascii2.f
Debug SizeOf(ascii2); displays 4

Is it normal? What if wanted the size of a variable named for example 'ascii.f' ?

Syntax
Size = SizeOf(Type)

Description
SizeOf can be used to find the size of any complex Structure, built-in type (word, float, etc.), Interface or even ReferenceLink "variables" "variables" (Structures with same name as variable take precedence). This can be useful in many areas such as calculating memory requirements for operations, using API commands, etc.

So, yes, it es normal.

To complete the answers of Stargate and juergenkulow, "character" is a pre-defined keyword.

Code: Select all

Define character.Q ; here, an error should occur.
Debug SizeOf(CHARACTER); displays 2

Define character2.q
Debug SizeOf(character2); displays 8

[juergenkulow]

Code: Select all

Structure Character
  c.c
EndStructure

"Character" is a pre-defined structure. You can find it under Tools Structure Viewer C.

Good one.
This is one of the beloved features of PB
