Discard

Frees up memory used for vectors. This does not destroy the vectors, just removes any copies that reside in RAM. The data is always stored on disc and can be recovered to RAM when needed.

Discard [/vec <vecname>] | [<groupname>]

Parameters

/vec	If specified vecname specifies a single vector.
groupname	Name of group data is to be discarded. Use current group if omitted.

Notes

/vec is specified. It does not delete the vectors altogether as they are still stored on disc in the temporary file. After discarding a group, it is still possible to plot all vectors that it contains.
