f p1 p2 p3 p4 ...
This causes a
GEN subroutine to place values in a stored function table for use by instruments. p1 Table number (from 1 to 200) by which the stored function will be known
. A negative number requests that the table be destroyed.
p2 Action time of function generation (or destruction) in beats.
p3 Size of function table (i.e. number of points)
Must be a power of 2, or a power-of-2 plus 1 (see below).
Maximum table size is 16777216 (2**24) points.
p4 Number of the GEN routine to be called (see GEN ROUTINES).
A negative value will cause rescaling to be omitted.

p6 | Parameters whose meaning is determined by the particular GEN routine.

Table space is allocated in primary memory, along with instrument data space. The maximum table number has a soft limit of 200; this can be extended if required.
An existing function table can be removed by an f statement containing a negative p1 and an appropriate action time. A function table can also be removed by the generation of another table with the same p1. Functions are not automatically erased at the end of a score section.
p2 action time is treated in the same way as in i statements with respect to sorting and modification by t statements. If an f statement and an i statement have the same p2, the sorter gives the f statement precedence so that the function table will be available during note initialization.
An f 0 statement (zero p1, positive p2) may be used to create an action time with no associated action. Such time markers are useful for padding out a score section (see s statement).
