is one of the device-dependent functions listed in Table 14-4
on page 14-68.
param1 input
INT:value
is one of the parameters listed in Table 14-4

depends on the device and the value supplied in the
function parameter.

value is retained for disk files; for SETMODEs on other devices, this value
depends on the device and the value supplied in the
function parameter.
last-params output
INT:ref:2
returns the previous settings of
param1 and param2 associated with the current
function. The format is:
last-params[0] = old param1
last-params[1] = old param2 (if applicable)
