hello again. sorry for being a bit vague above. ok, here is what i have done so far;

1. i go to PRGM, choose NEW.

2. i then name the PRGM whatever i want

3. i pick the "programming words" off the CATALOG

4. i then type the formulas above (i have tried all of the ones stated here)

for example;

Prompt A,B

100A/B=>C

Disp C

4. i then run the program by pressing PRGM and picking it

2. i press ENTER and the calculator asks for, A=?

3. i type a numeric value for A and then press the ENTER key again

4. the calculator asks for, B=?

5. i type a numeric value for B and then press the ENTER key

6. i get the eorro

ERR: SYNTAX

1. quit

2. go to

7. if i press GO TO it goes back to the formula and the cursor blinks on the > character.

by the way, this > character is the arrow that is on the STO key.

so, what am i doing wrong???

all i want is to calculate a PERCENTAGE INCREASE or DECREASE between two given numbers.

as well as to calculate a PERCENTAGE of one number.

please help… i am not sure what else to do?!?!?!?!?

i thank you all kindly.
