I have a calculation the result of which is a container. The calculation checks for the system platform.

Case ( Get ( SystemPlatform ) = -1;

"imagemac:/Images/FolderBW/ & ImageName ".jpg";

"imagewin:/F:/FolderBW/ & ImageName ".jpg";)

I now need to test for another condition: if the image is Black and White or Colour.

Case ( ColourSign ≠ "Colour";

"imagemac:/Images/FolderBW/ & ImageName ".jpg";

"imagemac:/Images/FolderColour/ & ImageName ".jpg";)

How would I combine these calculations so that I check for the system platform and the ColourSign field.

Case(

Get ( SystemPlatform ) = -1 ; "imagemac:/Images/" & If ( ColourSign ≠ "Colour"; "FolderBW/" ; "FolderColour/" ) & ImageName & ".jpg";

"imagewin:/F:/" & If ( ColourSign ≠ "Colour"; "FolderBW/" ; "FolderColour/" ) & ImageName & ".jpg"

)

or simpler:

Let(

cond = If ( ColourSign ≠ "Colour"; "FolderBW/" ; "FolderColour/" ) & ImageName & ".jpg" ;

Case( Get ( SystemPlatform ) = -1 ; "imagemac:/Images/" ; "imagewin:/F:/" ) & cond

)

Thank you Daniele

BEWARE: you are only checking for PowerPC based Macs with -1 result. The function also returns +1 for Intel Macs - use:

Abs (Get (SystemPlatform)) = 1
