Check the following codes.Characters in MB0 to MB3 converted to hex equivalent and stored in MB10 to MB13. Finally hex equivalent is calculated by: hex=(MB10+ (MB1116) + (MB1216^2) +(MB1316^3) ) The codes should be modifed for error detection [code] L 0 T #BUFFER L P#M 0.0 LAR1 LAR2 L 4 LP: T #Zählung A( L MB [AR1,P#0.0] L 65 >=I ) A( L MB [AR1,P#0.0] L 70 <=I ) JCN SND L MB [AR1,P#0.0] L 55 -I T MB [AR2,P#10.0] JC END SND: NOP 0 A( L MB [AR1,P#0.0] L 48 >=I ) A( L MB [AR1,P#0.0] L 57 <=I ) JCN END L MB [AR1,P#0.0] L 48 -I T MB [AR2,P#10.0] END: NOP 0 +AR1 P#1.0 +AR2 P#1.0 L #Zählung LOOP LP L MB 11 L 16 I L MB 10 +I T #BUFFER L 256 L MB 12 I L #BUFFER +I T #BUFFER L 4096 L MB 13 I L #BUFFER +I T #BUFFER T MW 200 [/code] Attachment 1.pdf (601 Downloads)
