Use this template for ROMCalls on calculators that don't use banked OS calls. Simply replace every occurance of bcall/BCALL/b_call with romcall/ROMCall/call.

The BCALLs are named by their b_call address, in hexadecimal. An example is [[83Plus:BCALLs:4009]].

This will cause your page to show in the appropriate categories. (Change the ProveTheRiemannHypothesis, 0042, and Utility to match your call. Also, change the 83Plus to whatever category, and change the BCALLs to ROMCalls if needed.) You may put a BCALL in any number of "By Name" categories. Put it in all the ones that make sense.

This B_CALL proves the Riemann Hypothesis, giving a proof under the required number of pages. It does this by randomly guessing proofs until it finds one that works. Needless to say, the calculator's batteries will run out before this B_CALL completes.

This B_CALL is essentially equivalent to the BASIC Disp function.

Synopsis

Official Name: FormDisp

BCALL Address: 497E

Displays the value in OP1.

Inputs

  • OP1: Any printable TI-BASIC value.

Outputs

  • Value converted to string and displayed

Destroys

  • Almost certainly destroys all registers as well as OP3-OP6; I haven't checked

Comments

This B_CALL is essentially equivalent to the BASIC Disp function.

Example

	ld hl,MatAName
	rst rMOV9TOOP1
	B_CALL FormDisp
 
MatAName:
	.db MatObj, tVarMat, tMatA
