Scratch Files

The environment variable HDS_SCRATCH is used on UNIX systems to define the directory in which HDS will create scratch container files to hold temporary objects created with DAT_TEMP. When creating a scratch file, HDS will use the file name:

$HDS_SCRATCH/$<$filename$>$

where $HDS_SCRATCH is the translation of this environment variable. If HDS_SCRATCH is undefined, then the file name will be used alone, so that scratch files will then be created in the current directory.
