Hi I was wondering how you can write a super long string in
ASM, I want it for CGI's
Does the function StdOut only take up to so many characters
Anyway I find I have to do this
string1 db "yyyyyyyyyyyy" <----strings much longer
string2 db "xxxxxxxxxxx"
string3 db "zzzzzzzzzzzz"
invoke StdOut , addr string1
invoke StdOut , addr string2
invoke StdOut , addr string3
when I wish I coud just do this
string db "yyyyyyyyyyyyxxxxxxxxxxxxxxzzzzzzzzzzzz"
invoke StdOut, addr string
Is there away to do this?
Thanks

I haven't tried it, but I guess this might work?
lea eax,string
@B: invoke StdOut, eax ; returns bytes written
lea eax, string[eax] ; end of string written
cmp BYTE PTR [eax],0
jne @BThanks BitRake, I haven't tried it but that looks like it will work,
I did try something other than StdOut, and I still had the same problem.

invoke WriteFile, hStdOut, addr httpHeaders, len_httpHeaders, addr BytesWritten, NULL
This is a line from what Thomas showed me in November, beasically what I'm sure you already know, there are other ways to print to a screen besides StdOut, but I believe as I remember having the same problem of limited output
Thanks Andy981

That is what StdOut does - it is just a wrapper around the API you posted. ;) Look on MSDN for the console functions for many other ways to write to the console.
lea eax,string
@B: invoke StdOut, eax ; returns bytes written
lea eax, string ; end of string written
cmp BYTE PTR ,0
jne @B
It works, but I have not fully bench tested it, I'll have to make a giant string.

That was excellent code, but now I remember why I asked this question.
It seems that you just can't declare a string in ASM
like string db "God awfully long String............." goes many lines
And not get this compile error
fatal error A1009: line too long
See I made a program in C that can take a html page and automatically
create a printf ("God awfully long String..............",
".....................................................");
printf statement, and it's cool because it saves you lots of time making cool CGI's in C , takes care of all the "" and other little perks.
Now I remember why I did not write another program in C to make giant ASM string declarations for the same purpose
It can be found somewhere here

I guess were victims of error A1009: line too long

It's a long standing assembly language practice to create long strings (or any large block of data) by splitting it over several data lines:
CR equ 13
LF equ 10
LongString db 'First part of string, '
db 'Second part of data, '
db 'End of line 1.', CR, LF
db 'Start of second line, '
db '..., '
db 'End of data'
ActualLength equ $-LongString
db 0 ; add this if creating an ASCIIZ stringString Length is only limited by your imagination. StdOut is based upon WriteFile (theoritically). Therefore you can print a string up to 4GB in size. And you can print 2 strings for a total of 8GB. If you put a null at the end of String3, call StrLen, you can use Write File to print all three at once if they are contiguous.
BTW, FAsm has the file directive, which allows you to place the file contents right into the output.

What does this part mean and how would I use it for ?
By the way Thank You TenKey , I tested what you gave me and it worked great, I believe I created a long enough string that before would have gave me an error
Thanks Andy:alright:
ASCIIZ is another name for a zero (NUL) terminated byte (ASCII/ANSI/ISO) string.
$ is the current value of the location counter, and ($-BeginningOfData) gives the number of bytes from BeginningOfData to the byte before the EQU.
Some functions, like WriteFile, do not use zero-terminated data. They use a size value instead of relying on a terminating character. This allows the function to handle either binary or text data.

How do add single quotes to a string like this
LongString db 'First part of string, '
LongString2 db 'First part of of many part's , '
that single quote will give you an error
LongString db 'First part of string, '
LongString2 db 'First part of of many part's , '
that single quote will give you an error
JUst add another single quote
:stupid:
:stupid:
Just rename the html file or part needed to infile.htm
and have it in the same directory as this program and it'll create a text file
like this
LongString db 'First part of string, '
db 'Second part of data, '
db 'End of line 1.', CR, LF
db 'Start of second line, '
db '..., '
Saves time if you like doing asm cgi's
