Scratch directory

If you do

Spike n1=10 n2=10 > Junk.H

and get something like

output(): No such file or directory
Spike: output() unable to open output file /sepcd2/scr/joe/_Junk.H@

You need to create a subdirectory with your username under the directory

/sepcd2/scr

Alternatively, read the section ``History files and datapaths'' in the main body of the text and learn how to use datapaths.
