Origin Version (Select Help-->About Origin): 7.5 SR5
Operating System: XP Home
In Origin C, it seems that it can not keep the case of the input. It always change it to upcase. For example, in OriginC:
int test(string sWks)
{ printf("sWks' name is:%s\n", sWks);
return 1;}
Afer compiling, I use this function in script window:
test("d")=
It always gives:
sWks' name is:D // note D, insted of d
TESTD("D")=1
How to solve this?

What Mike said is right.
I did further test. It seems the return type of the OC function is related.
void test1(string sWks)
{
printf("test1 sWks is:%s\n", sWks);
}
int test2(string sWks)
{
printf("test2 sWks is:%s\n", sWks);
return 1;
}
%R="ddDD";
test1(%R);
test1 sWks is:ddDD
test2(%R)=;
test2 sWks is:DDDD
TEST2(ddDD)=1

Literal strings are often converted to upper case when passed from LabTalk to Origin C. Passing the string as a letter variable is no better...
%A=d;
test(%A)=;
sWks' name is:D
TEST(d)=1
The solution is to use Origin 7.5's new $ string variable...
strVar$=d;
test(strVar$)=;
sWks' name is:d
TEST(STRVAR$)=1;
See the Programming Guide for more about $ string variables.
LabTalk Language Reference > Overview... > Data Types > String Variables
...Note that a letter string variable will work if you use LT_get_str to get its value.
int test2(string strLetter)
{
char chBuffer[16];
LT_get_str("%" + strLetter, chBuffer, 16);
printf("sWks' name is:%s\n", chBuffer);
return 1;
}
%A=d;
test2(A)=;
sWks' name is:d
TEST2(A)=1

After compiling asteria's test code I also noticed the following ...
test(CCcc);
sWks' name is:CCcc
test(CCcc)=;
sWks' name is:CCCC
TEST(CCCC)=1
test("CCcc")=;
sWks' name is:CCCC
TEST("CCCC")=1
test("CCcc");
sWks' name is:CCcc
