Allow temporary local variables in formula tools

[haraldharders]

It would be useful to allow for temporary local variables in formula tools. This could make code shorter, better readable, easier to maintain and help to avoid auxiliary columns which have to be deleted afterwards.

Arbitrary example for illustration:

if Length([Col1] + [Col2] + [Col5]) > 50 then
    Left([Col1] + [Col2] + [Col5], 48) + "..."
else
    [Col1] + [Col2] + [Col5]
endif

versus

tmpstr = [Col1] + [Col2] + [Col5]
if Length(tmpstr) > 50 then
    Left(tmpstr, 48) + "..."
else
    tmpstr
endif

The idea is that the temporary variable has limited validity inside the formula for a specific cell.

@haraldharders Really interesting idea. @jdunkerley79 's alteryx abacus would allow something similar to what you're after. It would be great if they could build something like this into the product itself without having to use a third party addin.

if Length(VarTextWrite("tmpstr",[Col1] + [Col2] + [Col5])) > 50 then
    Left(VarTextRead("tmpstr"), 48) + "..."
else
    VarTextRead("tmpstr")
endif
