#154367 - Why You Were Content Dependant Responding to: ???'s previous message |
Here is why your program is content dependant:
You are having the program try to execute through the message text as code. Depending on what you put into that message area the processor would "see" different types of instructions of various sizes. By the time it got to the place you load registers to write the message your load of the length and/or the DPTR load may not execute correctly due to the previous "message code" causing misalignment with the start of each opcoode.
