a simple question about strings [message #27012]

Hello.

I'm trying to format some data into one long line of various types of data.

My simple problem is that I am out of room to write the code on one line.
Normally, you can use the '$' to continue your code on the next line.
However, this does not work inside strings. Is there an analogous character
or magic combination of characters that does the same thing? If not, how
can I format my ridiculously long and complex output?

Thanks in advance.

Pick your poison...

IDL> print, strjoin(strtrim(indgen(5),2))
01234
IDL> print, indgen(5), format = '(5I1)'
01234
IDL> print, strcompress(strjoin(indgen(5)),/remove_all)
01234
IDL> print, string(indgen(5), format = '(5I1)')
01234

I'm sure there are other means, too.

Use STRJOIN, e.g.

IDL> a = strcompress(indgen(5), /remove_all)
IDL> help, a
A STRING = Array[5]
IDL> print, a
0 1 2 3 4
IDL> b = strjoin(a)
IDL> help, b
B STRING = '01234'
IDL> print, b
01234

Hello,

Little correction:

The command
> A = string(indgen(5))
produces an array of five elements:
[0 1 2 3 4]
