It was broken on OSI and ; KIM, and okay on APPLE and CBM2, because ; these used a non-ZP INPUTBUFFER. ; Microsoft fixed this somewhere after KIM ; and before MICROTAN, by using beq instead ; of bne in the ZP case. .ifdef CBM1 ldy #>(INPUTBUFFER-1) ldx #<(INPUTBUFFER-1) .else ldx #<(INPUTBUFFER-1) ldy #>(INPUTBUFFER-1) .endif .if .def(CONFIG_2) && (!.def(CONFIG_NO_INPUTBUFFER_ZP)) beq L2AF8 ; always .else bne L2AF8 ; always .endif L2AF0: .endif bmi FINDATA .ifdef CONFIG_FILE lda Z03 bne LCB64 .endif .ifdef KBD jsr OUTQUESSP .else jsr OUTQUES .endif LCB64: jsr NXIN L2AF8: stx TXTPTR sty TXTPTR+1 ; ---------------------------------------------------------------------------- INSTART: jsr CHRGET bit VALTYP bpl L2B34 .ifndef CONFIG_SMALL ; GET bit INPUTFLG bvc L2B10 .ifdef CONFIG_CBM1_PATCHES lda #$00 jsr PATCH4 nop .else inx stx TXTPTR lda #$00 sta CHARAC beq L2B1C .endif L2B10: .endif sta CHARAC cmp #$22 beq L2B1D lda #$3A sta CHARAC lda #$2C L2B1C: clc L2B1D: sta ENDCHR lda TXTPTR ldy TXTPTR+1 adc #$00 bcc L2B28 iny L2B28: jsr STRLT2 jsr POINT .ifdef CONFIG_SMALL jsr LETSTRING .else jsr PUTSTR .endif jmp INPUT_MORE ; ---------------------------------------------------------------------------- L2B34: jsr FIN .ifdef CONFIG_SMALL jsr SETFOR .else lda VALTYP+1 jsr LET2 .endif ; ---------------------------------------------------------------------------- INPUT_MORE: jsr CHRGOT beq L2B48 cmp #$2C beq L2B48 jmp INPUTERR L2B48: lda TXTPTR ldy TXTPTR+1 sta INPTR sty INPTR+1 lda TXPSV ldy TXPSV+1 sta TXTPTR sty TXTPTR+1 jsr CHRGOT beq INPDONE jsr CHKCOM jmp PROCESS_INPUT_ITEM ; ---------------------------------------------------------------------------- FINDATA: jsr DATAN iny tax bne L2B7C ldx #ERR_NODATA iny lda (TXTPTR),y beq GERR iny lda (TXTPTR),y sta Z8C iny lda (TXTPTR),y iny sta Z8C+1 L2B7C: lda (TXTPTR),y tax jsr ADDON cpx #$83 bne FINDATA jmp INSTART ; ---NO MORE INPUT REQUESTED------ INPDONE: lda INPTR ldy INPTR+1 ldx INPUTFLG .ifdef OSI ; CONFIG_SMALL && !CONFIG_11 beq L2B94 ; INPUT .else bpl L2B94; INPUT or GET .endif jmp SETDA L2B94: ldy #$00 lda (INPTR),y beq L2BA1 .ifdef CONFIG_FILE lda Z03 bne L2BA1 .endif lda #ERREXTRA jmp STROUT L2BA1: rts ; ---------------------------------------------------------------------------- ERREXTRA: .ifdef KBD .byte "?Extra" .else .byte "?EXTRA IGNORED" .endif .byte $0D,$0A,$00 ERRREENTRY: .ifdef KBD .byte "What?" .else .byte "?REDO FROM START" .endif .byte $0D,$0A,$00 .ifdef KBD LEA30: .byte "B" .byte $FD .byte "GsBASIC" .byte $00,$1B,$0D,$13 .byte " BASIC" .endif
