Rif.: Use a variable for the integer in Fmt offset modifier

[Blairma]

I'm trying to pluck values out of a long array of comma separated string
values.
I'm doing this within a loop and would like to use the loop interation to
point to the starting point in the array.

Here's what I have working so far:
Fmt (scratch,"%s<%s[i0t44]",transmitBuf);
Works great.

Now if I go in and change i0 to i3 then my modifier doesn't start looking
for a comma "," until after the 3rd character. Still working great. However....

If I try to use an integer called "loop" instead of the literal offset
value it blows up:

Fmt (scratch,"%s<%s[iloopt44]",transmitBuf);

Is there a way that I can use a variable for the integer portion of the
offset modifer?

Thanks All!

You can look into this help page: search for "Using Asterisks (*) Instead of Constants in Format Specifiers" section, which I suppose is the direct solution to your question.

Nevertheless, I wander if this example can be more user friendly: String with Comma-Separated ASCII Numbers to Real Array

Hi Roberto

Thank you. I actually need to use a symbolic value for the interger section of the modifer vs. the specifier.

So, in my example:

Fmt (scratch,"%s<%s[i0t44]",transmitBuf); 

I want to make the following substitution (Assume z=0)

Fmt (scratch,"%s<%s[izt44]",transmitBuf);

Some background...

I'm looking to loop index through a long CSV string array (transmitBuf) that looks like this:

1,PEEP,7,6,,,21,20,

So on my first loop when I use the following:

Fmt (scratch,"%s<%s[i0t44]",transmitBuf); 

scratch = "1"

... Perfect. I now do a string length of scratch (which equals 1)

and add 1 to it, I'm ready for my next loop which would

literally read like this:

Fmt (scratch,"%s<%s[i2t44]",transmitBuf); 

However, I want to put this inside a loop, so I would like to

increment a variable (++z) and use the following:

Fmt (scratch,"%s<%s[izt44]",transmitBuf); ---- Ka-Boom!

So it's the use of the variable in the modifer that blows up

the Fmt command.

appreciate any thoughts...

Thanks

Mark

Seems you haven't read carefully my first link: what about

Fmt (scratch, "%s<%s[i*t44]", z, transmitBuf);

Thanks Roberto,

Let me look into that.....
