Re: sizeof() on String type with a fixed size of 10

I have a String type which is named "sStr" with a fixed size of 10.

When i use sizeof(sStr) i get "4".

Why?

Hi Raz,

sizeof() is returning the size of the pointer that is pointing to the buffer containing the string.

To get the number of characters in the buffer you can use the len() procedure.

Jason

Hi,
if i dont initiale the sStr variable, the len() function returns 0.

how can i get the "fixed size" of the variable?

Define it fixed string in the Variable Properties window, see on-line help "String Data Types" topic.

Re: sizeof() on String type with a fixed size of 10

Len() returns the current length so it will be zero until you assign to it a string, sizeof returns the number of bytes that this variable takes - that will be always 4 for a string. You can also use array of char:

acChars: char [100]

print sizeof acChars

will print 100
