Data Block Size

 Dear OmegaPro.

I am very appreciation for your answer.

But if you can try to read all request, you can see "and".

Not only size intrested me.

I need example, that uses "size of db", because it need for program cycle.

Thank you for your help.

Could you be more explain your need please ?

Do you want to know the minimum, maximum and the average of all the values in the whole db ?
Or do you know the structure of the db (because you said you only know the db number) so you know on which position you have a value which represents minimum , maximum, etc... of a certain existing 'struct'ure ?

Hi

see attached source. Written in Step7 v5.4.

Change source file extension to .awl and insert.

Use following symbols:

Average         MD    104       REAL
CalcStat         FC      1         FC      1
Maximum        MD    112       REAL
Minimum        MD    108       REAL
Total              MD    100       REAL
Values           DB      1         DB      1

Function was briefly tested. Hope it helps. Good luck.
