VFR Programming Language
4.1 BNF of VFR
Character sequences that are in bold are key words. Keywords are case insensitive. The same
extensions to BNF used to describe VFR are used here. Where elements are on separate lines in the
BNF, those elements are required. VFR comments start with ‘//’ and end at the end of the line.
The following ‘meta’-language elements are allowed on any line.
::=
::=
::=
define | define
redefine | redefine
include file-path
Note: No comments are allowed on a file path line. The entire line from the first non-blank character
following the include is taken as the file name.
::=
*
endformset
formset guid= title= nvstore=
Note: is the current placeholder for the variable path.
::=
*
endform
form formid= title=
::= | | | | | |

Note: It is expected that the compiler will automatically allocate the location information in most cases.
