I'm not sure how exactly you want your program to work, but I'll give you a few basic details that should provide most of what you need.

To get a pointer to an OS variable in RAM:
GetCalc("var_name")

To find the size of an OS equation, program, appvar, or string:
{pointer_to_var-2}?

To create an OS variable and get a pointer to it:
GetCalc("var_name",size)

To copy data from one memory location to another:
Copy(copy_from,copy_to,size)

Using these pieces of information, you should be able to create a simple Axe program that creates a program and copies the contents of Str9 into it. :)



If you'd like to see a simple Axe program to do this, I'll put two such Axe programs in spoilers. The first will be the normal version, which should be a bit simpler to understand, and the second will be the optimized version. But I feel confident that you won't need to peek to figure it out. :)

EDIT

So apparently I completely misunderstood the request. It was how to create a program whose name is in Str9, which makes a lot more sense. As an added detail, TiAddict added in IRC that he wanted the program to be created with a size specified by the OS variable L. Here's how I would do it. And don't worry about that hexadecimal number, that's just a free memory location that's well-sized for what we need and shouldn't be used by anything else, which I got from thepenguin77's excellent list.

.STR9PROG
?9D8A?°Name
'prgm'?Name
GetCalc("Str9")?S
Copy(S,°Name+1,{S+2}??Z)
 and 0?{Z+°Name+1}
GetCalc(°Name,float{GetCalc("varL")})

.STR9PROG
ᴇ9D8A→°Name
'prgm'→Name
GetCalc("Str9")→S
Copy(S,°Name+1,{S+2}ʳ→Z)
 and 0→{Z+°Name+1}
GetCalc(°Name,float{GetCalc("varL")})

Optimized :
.STR9PROG
ᴇ9D8A→°Name+1→°Name1
'prgm'→Name
GetCalc("Str9")→S
Copy(,°Name1,{S+2}ʳ→Z)
 and 0→{Z+°Name1}
GetCalc(°Name,float{GetCalc("varL")})

-5 bytes
 

Thank you all for helping me with this, but whenever i run it, (im sure i typed it right, i checked 5 times now) it's not creating the program!!
maybe my calc is being stupid

Hmm, it seemed to work in my tests. The only reasons I can think of why it wouldn't work are bad name input (Str9), size input too large (L), the code being copied incorrectly, or a bad/old version of Axe.

If you can post the source 8xp and tell me what version of Axe you're using, or if you can post the compiled 8xp, I should be able to tell you if the problem is either of the latter two possibilities. The former two possibilities you could check. Alternatively, if you're testing this on your calculator and can't easily transfer files to a computer, if you've made no changes to my code and could tell me the size of the compiled program STR9PRGM in the memory management menu and your version of Axe, I may be able to tell you if the problem is one of the latter two possibilities, although I couldn't pinpoint a copying error.
