I was trying to figure out how is the best way to separate individual
letters in a textfile parsed by puredata.
This is for generate real time bytes for an alphanumeric display.

is something that I can do directly from keyboard this way:

[key] (entry "abc 123" )

[prepend add2]

[97 98 99 32 49 50 51]

*BUT in the exemple:

[abc 123] -> entry inside a symbol
|
|
[pd thisparser]
|
|
[97 98 99 32 49 50 51]

how could I separate the characters and convert them individually to ascii
code inside the parser?

[moocow/any2string] outputs symbols as lists of ascii numbers. If your display is a hardware thingy on a serial port you can use the [print( message with [comport] to send the symbol as ascii.
