@ -13,7 +13,7 @@ This wrapper renders `dc` more usable as a command line calculator by:
- defining commonly used macros for more complex operations
- saving precision, top of stack, and registers 0 to 9 ("memories")
from one invocation to the next in the status file `$HOME/.wdcrc`
- saving last top of stack value in `/tmp/wdc-$USER` for further direct use
- saving last top of stack value in `${TMPDIR:-/tmp}/wdc-$USER` for further direct use
(change file name in the source, if desired)
