FileSwitch$..$CSD

The environment variable FileSwitch$ <FileSwitch$CurrentFilingSystem> $CSD isn’t set at boot.

DIR @ will set it, but given it’s not set at boot can it be relied upon to be correct at all other times?

EDIT: I forgot to add that I’m using it to workaround the fact Back can error if the previous Dir changed filesystems.

SetMacro Alias$StoreCSD Set Previous$CSD X|MX DIR @|MX StoreCSD2|MIF "|<Previous$CSD>"="X" THEN Set Previous$CSD *|<FileSwitch$CurrentFilingSystem>
Set Alias$StoreCSD2 SetEval Previous$CSD "|<FileSwitch$CurrentFilingSystem>:"+(FileSwitch$|<FileSwitch$CurrentFilingSystem>$CSD)
Set Alias$RestoreCSD IF ("|<Previous$CSD>" LEFT 1)="*" THEN DO |<Previous$CSD> ELSE Dir |<Previous$CSD>

Essentially use StoreCSD before a Dir followed by RestoreCSD instead of Back to go back to the original directory.

EDIT: I’ve spotted another quirk with is related to this. After a fresh boot, OS_GBPB 6 returns “Unset” despite *. definitely showing the CSD is the root of the boot drive.

Sorry, I misread your post. the two .. in the title and the > in the post confused me.
