AS memory is used, it is possible tO test for remain- ing memory and take appropriate steps as it is de- pleted, without having tO worry about destruction Of the assembly routine. は has been suggested that asys- tem monitor be used tO place the routine in proper high memory. The most practical method for modest length routines is tO 'poke' it intO the proper memory slOt, as ー did here.ln bOth examples, the data is placed in 'data' statements and 'read' (and poked) intO memory. Don't be confused by the &H that precedes each number. This simply designates that the following number is hexadecimal. Short routines can be included with the main program. Longer routines should be located in separate programs, chained from the main program, and executed tO memory. Then the main program can continue. The primary thing tO note about the subrou- tine is the 'ret' mnemonic. This must be included in bOth 'usr' and 'call' methods in order tO return tO the maln program. 200 DATA & H54 ′ & HOD ′ & HOA ′ & H24 ′ & H54. & H68 ′ & H69 ′ & H73 ′ & H20 ′ & H69 ′ & H73 ′ & H20 10 20 30 40 50 60 70 80 9 0 100 115 120 130 135 140 150 160 170 180 190 200 210 220 PRINT CHR$(27);CHR$(43) : Ræ CLEAR SCREEN THIS IS A TEST OF THE CALL FUNCTION" PRINT PRINT:PRINT:PRINT PRINT "THE PRCERN'I CALL WILL BE SUMMONNED" PRINT I = & H8100 READ A IF A=&HFF THEN 120 : R ひ 1 ls the message delimiter found? 10 20 30 40 50 60 70 80 90 100 115 130 135 140 150 170 180 190 210 PRINT CHR$ ( 27 C 日 R$ ( 4 3 ) : REM CLEAR SCREEN PRINT 物 THIS IS A TEST OF THE tÆR FUNCTION" PRINT: PRINT: PRINT PRINT "THE PRCGRAH USR3 WILL BE SUMMONNED" PR INT I = & H8100 : Ræ STARTING ADCRESS OF SUBROUTINE READ A IF A=&HFF THEN 120 I ,A: REM BYTES INTO MNORY I=I + 1 110 GOTO 70 R EM 120 DEF USR3 = & H8100 X=USR3(1) R24 PR INT PR INT "THE USR3 SUBROtnINE IS DATA & HC9 ′ & H54. & H68. & H69 ′ & 日 73 を & H20 ′ & H69 ー & H73 ′ & H20 ′ & H61 ′ & H20 ′ & 日 50 160 DATA & H11 ′ & H11 ′ & H81 ′ & HOE ′ & H09 ′ & HCD ′ 05 ′ 00 ′ & H11 ′ & H24 ′ & H81 ′ & HOE H09 X)NE" DATA & HCD ′ 05.00 DATA & H52 ′ & H4F ′ & H4D ′ & H50 DATA & H4D ′ & H45 ′ & H53 ′ & H53 220 DATA & H31 ′ & H20 ′ & HOD ′ & HOA ′ & H24 ′ & 日 FF Figure 2.
