By "Tab"

This works:
fd := fopen("C:/ZZZ_TEST4.txt", WRITE);
fprintf(fd, "A");
fprintf(fd, " "); #one Tab between ""
fprintf(fd, "B");
fclose(fd);

See Tab.mw

\t

The control character of a tab can be printed by using an escaped character with backslash (\).

fprintf("c:/temp/text.txt","%a\t%a",A,B):

fclose("c:/temp/text.txt");

And now that file text.txt contains,

A	B

with a tab between them.

See ?backslash and ?printf

no blank, tab!

HI,

thanks for the answer! But thats not exactly what I want. I don't need a blank sign. I need this "space" or "formatting" like if you press the "tabulator"-key. The problem is, that this txt-file will be opened and used by a machine for etching some chemical stuff. And this machine only recognizes "tabs" like from the tab-key. Do you have any idea how I could produce that? :-(

escaped symbols

@Xilyte

See ?backslash for more escaped symbols. Most of them (includding \t i.e. 09h in ascii) same as in pure "c" language.
