Problem with toupper

[ECACE]

I am having trouble getting toupper to work correctly. The code below works when I manually go through each char and convert it. But if I use the for loop and try to convert it, it does not work. It compiles fine, but for example if I put in "ht" which is one of the commands in lower case, I would expect to get back HT, but instead I get ht. So, it looks like you can't use a for loop for converting chars with toupper??? That doesn't sound right. Please tell me I am just doing something stupid here.

I want to be able to use the commented out for loop to do the conversion, instead I am having to do the manual: COMMAND[0] = toupper(COMMAND[0]);
Otherwise it just isn't converting it. Entering upper case returns uppercase and entering lower case returns lower case.

Also, at the begining of the program, I do have:

#device PASS_STRINGS = IN_RAM //Needed for String functions to work

and I have included the string headers:
#include <string.h> //Header file for string manipulations
#include <stdlib.h> //Header File for ascii manipulations

See this thread. It has several solutions.

Another solution is to use a temp variable:

In your example then, would I need to have all menu possibilitys defined:
char COMMAND[5] = {"ht"}
...
...
...

One for every possible menu entry? If that's the case, I wouldn't want to do that. I prefer the one you had in the post:

Old post, but I have been going back and forth with CCS on this one. They have found the bug and reported back that it will be fixed in the next update. Fingers crossed and hope it works!
