Micro SD find

Hello all, I am completely new to the SD card shield. I have 2 questions at this point that are purely conceptual at this point since I have not started coding yet.

  1. can I run code on the processor after it reads it from the sd card?

  2. If I have only 1 .txt file on the card, and it is composed of basically:
    123345=this is a test
    154646=this is a tester test of test
    154654=want this to work too
    .....

so that my code can look up "154654" and be returned with "want to work too" as a string.....

thanks,

Only if you write your own bootloader. Code has to be in FLASH memory to run. Only the bootloader partition can write into FLASH memory.

Yes, you can read a file until you find a pattern, then read the rest of the line and store that in a String object or character buffer.
