Hello,
It works exactly the same as format string in C-language 'printf'. You can find it
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HTML/_crt_format_specification_fields_.2d_.printf_and_wprintf_functions.asp
But with exceptions described in the user's guide (i.e. only floating point numbers are supported)
In the user's guide:
http://www.amibroker.com/f?strformat
Note 1: for numbers always use %f, %e or %g formatting, %d or %x will not work because there are no integers in AFL.
Note 2: as of now only numbers and arrays can now be used. For arrays 'selected value' is used
Best regards,
Tomasz Janeczko
