Disjunction of text and values

Postby Katjes » Thu Oct 02, 2008 6:49 am

After freezing e.g. the table with Johansen cointegration test results you can simply retrieve the cells content:

Code: Select all

scalar x = @val(tab1(12,3))

Code: Select all

%x = @str(tab1(10,3))

But how can I separate between text and values in one cell? The cell tab(1,3) contains e.g. "Included observations: 113", but I only want to select the value "113".
Thanks for helpful comments!

You can use some string functions to extract the number part of the string, and then convert that part into a number. The following example does this by searching for a ":" in the string, then converting the text following the ":" into a number:

Code: Select all

%temp = tab1(1,3)
!i = @instr(%temp,":")
%temp2 = @mid(%temp,!i+2)
!obs = @val(%temp2)
