How to print " in a string

[Jan Kromhout]

I need to print out over the serial. => t0.txt="9999"
In C I can use print("t0.txt=\"9999\""
Forth is not accepting the \, how should I program this in forth?

Cheers,

Jan

FF is a bit simple to keep the size down. with [CHAR] you can get the ASCII code for any character and print it with EMIT.
[CHAR] is for compilation mode, while CHAR works in interpretation mode.

: quote. ( n -- ) [char] " emit . [char] " emit ;

But the DOT word prints an extra space after the number which may not be what you wanted

: "" [char] " emit ;
: ... <# dup abs false #s rot sign #> type ;
: "". ( n -- ) "" ... "" ;

Here is an example quoting a string

: "".s ( a n -- ) "" type "" ;
: hello ( -- a n ) s" hello" ;
hello "".s 
"hello"
