Existing CAS commands --> Prime discussion

[Eddie W. Shore]

Testing the four "crement" commands in programming:

Code:

EXPORT TEST7788()
BEGIN
// CREMENT TEST
// EWS 2019-11-07
LOCAL a:=100;
LOCAL b:=5;
PRINT();

CAS.increment(a,b);
PRINT("+  "+a);

CAS.decrement(a,b);
PRINT("-  "+a);

CAS.mulcrement(a,b);
PRINT("*  "+a);

CAS.divcrement(a,b);
PRINT("/  "+a);

PRINT("-------");

a:=CAS.increment(a,b);
PRINT("+  "+a);

a:=CAS.decrement(a,b);
PRINT("-  "+a);

a:=CAS.mulcrement(a,b);
PRINT("*  "+a);

a:=CAS.divcrement(a,b);
PRINT("/  "+a);

END;

The results may show why these four commands are not in the catalog:

Code:


+  100
-  100
*  100
/  100
-------
+  increment(100,5)
-  decrement(increment(100,5),5)
*  mulcrement(decrement(increment(100,5),5),5)
/  divcrement(mulcrement(decrement(increment(100,5),5),5),5)
