TICKS
…
\
Returns the number of ticks from the real time
clock at execution time. With the quartz built in,
1 tick = 0.1 s. Without, it may be 10% more or
less. So the quartz is inevitable prerequisite for
the clock being useful in medium to long range.
TIME
…
DECM,
Recalls the time from the real time clock at ex-
ecution, displaying it in the format
hh.mmssdd
in
24h-mode. Chose FIX 6 for best results.

PRG
Executes the next step only if it is called from a
program that isn't a subroutine, i.e. if the pro-
gram running flag is set and the return stack
pointer points to an empty stack.
TRANSP

DECM
Takes a matrix
descriptor
in
X
and returns the
descriptor of its transpose. The transpose is
done in-situ and does not require any additional
registers or storage.
