   Print "RTRIM$: |", Rtrim$("                Trim a string                "), "|",CrLf$

Output:
RTRIM$: |                Trim a string|

Looks OK for me...

The exe in your attachment crashes indeed, but even with full symbols the test.asm you sent assembles to a 35k file - your exe has 45k. So it was produced with a different source. Can you post source and matching exe, please?

ok. I updated the library -- no crash
however, it still mess up the font

Try a MbCpAnsi=437 before the first Print. See the orange section here for details.

The standard code page for the console is normally "DOS code pages", 850 on my machine. The default for MasmBasic seems to be "Windows-1252".

Indeed. You can change that with MbCpAnsi=850

if I test the Rtrim$(" \r\n") macro nothing happens

Code Select Expand

proc_7 proc string:dword
    mov eax,Rtrim$(string)
    mov eax,string
    ret
proc_7 endp

returns " \r\n"

Yes, because Rtrim$() doesn't change the original string. Comment out the mov eax,string to get a pointer to the copy.
