Re: select vs. if-elseif

I have a similar approach to Birgitta. If in my mind I am thinking "this is a condition where a small number of variables have specific states" then I use a select.  If it's a more complex set of business rules such as "if it's a non-taxable customer, do A, else if we're in a special tax facility do B, else if the item has special considerations do C" then I go with an If/Elseif stack.

Even they are redundancy I use SELECT and IF/ELSEUF them "differently".

If I check different entries within the same variable(s), I use SELECT. For
examples

Select;
When FLDA = 'A';
When FLDB = 'B;
...
EndSL;

Or

Select
When FldX = 'A' and FldY = 'B';
When FldX = 'X' and FldY <> 'B'
When FldX <> 'A' and FldX <> 'X' and FldY = 'C'
...
EndSL

If I have to check different conditions I use IF / ELSEIF. For examples:
If FLDA = 'X' and FLDB = 'Y';
ElseIF FLDC = 1;
...
Else;
EndIf

Or
(Param3 and Param2 are different fields)
If %Parms >= %ParmNum(Param3) and Param3 > '';
ElseIf %Parms >= %ParmNum(Param2) and Param2 > *Zeros;
...
Else;
EndIf;

... but these are only my private rules
