You have to make a loop that will last a certain amount of time. A
common thing was to say something like
20 FOR I=0 TO 100:NEXT
-- varying the number after TO to produce a different length of delay.
Commodore BASIC is slow, but I'm sure a loop from 0 to 100 won't take
anywhere near 10 seconds; you can play around with it.
The more complex and more accurate way was to use the TI and TI$
variables to actually count off a given amount of time. If I remember
correctly, for 10 seconds it would be like this:
20 TI$="000000"
21 IF TI<(10*60) THEN 21
TI$ is a string that refers to the current system time (time since
poweron); the first two digits are hour, the second pair minutes, the
last two seconds. TI is a closely-related one that returns the number of
jiffies (1/60-second slices) in the system time. 10*60 converts jiffies
to seconds.
But I wouldn't impose this artificial wait; I certainly wouldn't want to
play a game that did that. Maybe you're just trying to make it more
period-correct by emulating 1541 loading times, in which case the delay
should be much longer ;)
