__FUNCTION__


Intrinsic define (macro string) set by the compiler

Syntax:
__FUNCTION__

Description:
Substituted with the quoted name of the current function block where used.

Its normal use is to report wrong values in debugging.

If __FUNCTION__ is used at the module level, the function name given will be "__FB_MAINPROC__" for the main module, or "__FB_MODLEVELPROC__" for a different module.

Examples:
Dim a As Integer

'...

If a < 0 Then '' this shouldn't happen
    Print "Error: a = " & a & " in " & __FILE__ & " (" & __FUNCTION__ & ") line " & __LINE__
End If


Error: a = -32767 in test.bas (__FB_MAINPROC__) line 47
