Hello,
I have found a possible issue with sprintf(). In the following script should not section 1
and 2 yield similar printed output? But note that bslash is empty after section 1 (output
included). Is this the intended behavior? OS = Win 7 64bit and gretl = 1.9.91cvs
#1
sprintf bslash "\\"
print bslash
#2
printf "\\"
Output:
gretl version 1.9.91cvs
Current session: 2014-07-03 17:35
#1
? sprintf bslash "\\"
? print bslash
#2
? printf "\\"

What's the date of your gretl build? I'm not seeing a problem here
with current CVS (and I did work a bit on sprintf fairly recently).

I just updated to today's CVS (2014-07-03) and got the same result. Could it be a
Windows problem?

Yes I can confirm this, which may not mean much because my OS parameters
here are identical. Also notice the following variation with four
backslashes:
<hansl>
#1
sprintf bslash "\\\\"
check = strlen(bslash)
print check
print bslash
#2
printf "\\"
</hansl>
which gives a string of length 1 and prints a single backslash here:
<output>
gretl-Version 1.9.91cvs

? sprintf bslash "\\\\"
? check = strlen(bslash)
Ersetzte Skalar check = 1
? print check
check = 1.0000000
? print bslash
\
#2
? printf "\\"

</output>

OK, there seems to be a platform-specific problem here. Not sure how
that could happen, but I'll look into it.

This is now fixed in CVS. Updated snapshots will follow tomorrow or
on Monday.
