Hey mates!
This time I got a very strange problem. I want to show a question on a LCD. For that i created a loop which takes every letter and draw it on the lcd. Here's my problem: You see the variable Q1_1 writtin down in the middle of the loop. How can I increment this variable? Sot that I get the next letter. I'm using Keil A166.
MOV R13, #00H drawQuest: MOV R15, #00H MOVBZ R15, Q1_1 ;CALL LCD_DW CMPI1 R13, #Q1_1_LEN JMP cc_NZ, drawQuest
Quest1: Q1_1 DB 'Which Color?' Q1_1_LEN EQU $-Q1_1 A1_1 DB 'CYAN' A1_2 DB 'PINK' A1_3 DB 'LILA' A1_4 DB 'GRÃœN'
Big thanks at all.
Have a nice time...

I would agree with Hans-Bernhard comments. If you are trying to write the string Q1_1 to a serial port (tx buffer register) or another fixed variable then the code could look like...
Assuming "out" is the variable or it could be the serial transmit buffer register you want to copy Q1_1 data too.
MOV R5,#0 Drawloop: MOVB RL4,[R5+#Q1_1] MOVB out,RL4 CMPI1 R5,#Q1_1_LEN JMP cc_SLT,Drawloop
