Example 1: This program determines which integer from 2
to N has the greatest number of factors.
EXPORT MAXFACTORS(N)
BEGIN
LOCAL cur,max,k,result;
1 ▶ max;1 ▶ result;
FOR k FROM 2 TO N DO
SIZE(CAS.idivis(k)) ▶ cur;
IF cur(1) > max THEN
cur(1) ▶ max;
k ▶ result;
END;
END;
MSGBOX("Max of "+ max +" factors for
"+result);
END;
In Home, enter
MAXFACTORS(100).
FOR STEP Syntax: FOR var FROM start TO finish [STEP increment]
DO commands END;
Sets variable var to start, and for as long as this variable
is less than or equal to finish, executes the sequence of
commands, and then adds increment to var.
