I used a guide from Ticalc.org. ANd the assembler gave me this code, could someone please tell me what's wrong? I have all the requirements that are required for TASM.

Heres the error that MS-DOS had given me.

C:\ASM\TASM>asm hello
==== Now assembling hello.z80 for the TI-83 Plus ====
TASM Z80 Assembler. Version 3.2 September, 2001.

tasm: Number of errors = 5
==== Errors!!! ====
==== Done ====

Here's the original code of the asm program.

.NOLIST
#INCLUDE "ti83plus.inc"
#DEFINE ProgStart $9D95
.LIST
.ORG ProgStart - 2
.DB t2ByteTok, tAsmCmp
b_call(_ClrLCDFull)
LD HL, 0
LD (PenCol), HL
LD HL, msg
b_call(_PutS) ; Display the text
b_call(_NewLine)
RET
msg:
.DB "Hello world!", 0
.END
.END


---Thanks.;)

I'm a newbie with the same problem. Getting the error on the b_call(...) lines. I noticed in the t83plus.inc include file there is a commented out section, see below. Does anyone have any clues?

;======================================================================
; Macro to call base code from an app,
;======================================================================
;
;rBR_CALL	EQU	28h		; NEEDED FOR APPS
;BRT_JUMP0	EQU	50h
;
;B_CALL macro   label
;	     RST     rBR_CALL
;	     DW      _&label
;       .endm
;
;B_JUMP macro   label
;	     CALL    BRT_JUMP0	     ; fixed location on page 0
;	     DW      _&label
;       .endm

OK, I got my code to compile in TASM by including the following at the top of the code just below the other #include directive:

#define B_CALL(xxxx) rst 28h \ .dw xxxx

I saw this in other examples and tried it. I don't know what this does yet, but it might help you along.
