Note: For mathematical operations with tagged quantities, the calculator will

"detag" the quantity automatically before the operation. For example, the left-

hand side figure below shows two tagged quantities before and after pressing

the * key in RPN mode:

Examples of tagged output

Example 1 – tagging output from function FUNCa

Let’s modify the function FUNCa, defined earlier, to produce a tagged output.

Use ‚ @FUNCa to recall the contents of FUNCa to the stack. The original

function program reads

« “Enter a: “ {“:a: “ {2 0} V } INPUT OBJ→ → a «

‘2*a^2+3‘ NUM » »

Modify it to read:

« “Enter a: “ {“:a: “ {2 0} V } INPUT OBJ→ → a «

‘2*a^2+3‘ NUM ”F” →TAG » »

Store the program back into FUNCa by using „ @FUNCa. Next, run the

program by pressing @FUNCa. Enter a value of 2 when prompted, and press

`. The result is now the tagged result F:11.

Example 2

– tagging input and output from function FUNCa

In this example we modify the program FUNCa so that the output includes

not only the evaluated function, but also a copy of the input with a tag.

Use ‚ @FUNCa to recall the contents of FUNCa to the stack:

« “Enter a: “ {“:a: “ {2 0} V } INPUT OBJ→ → a «

‘2*a^2+3‘ NUM ”F” →TAG » »

Modify it to read:

« “Enter a: “ {“:a: “ {2 0} V } INPUT OBJ→ → a «

‘2*a^2+3‘ EVAL ”F” →TAG a SWAP» »
