You are mistaken. There is a system-variable VARTYP (&HF636) which needs to contain value 3 and DAC+2 (&HF7F8) needs to contain the pointer to the string descriptor.

Re: basic usrdefs
I figured it 'all' out :-) the Tech-docs say DE holds a pointer to a string descriptor this is true for the argument that is passed as arg. However, for returning a string you do not only have to set DE to the new string descriptor, but also the 2byte location 0F7F8h (DAC). And i'm not even sure if DE is being used, but just to be safe :-) Changing the original descriptor i have not tried but i imagine it can do damage (leaks?). This i already tried before but... i did an increase to many.. the routine was supposed to convert strings like "A" to "rA"... "rA" + 1 = "A".. DOH! :-) anyway, an example -- descriptor: db 0,0,0 basic_callable_function: cp A,3 ret nz ;; not a string as arg ;; do stuff, maybe even change the 'descriptor' for returning ;; some other string besides a "" string LD DE,descriptor LD [0F7F8h],DE LD A,3 ret This will return a string with length 0. Upon return the string is copied! into the return string, which has it's own descriptor. Maybe a nice thing for the FAQ?

Re: basic usrdefs
no, a usrdef can return a string. In fact, when you give a string as argument, you get type-errors if you return a non-string (well on my 8235 anyway). Maybe i'm just doing something wrong but i havent figured out yet what it is. I've the msx2 technical handbook here from ASCII, but it's very brief on usrdefs.. It's pretty brief on anything actually :) The MSX1 Technical handbooks from Sony and Mickeysoft arent any better :/ Floris Maarten ter Huurne wrote: > > On Fri, 05 May 2000, Floris 'Tamama' van Gog wrote: > > > I'm making a little program in basic.

basic usrdefs
hi,
I'm making a little program in basic. In it i need to call some
assembler function i made that takes a string as arg, and returns _a
different string_
The assembler part does not change the arg-string data, but it changes
it's descriptor (3 bytes{len:offset}). The data i dont change because i
dont know if the string would fit.
Right now i have changed DE and that what DE pointed at (the string) but
i always get the same string back. What is going on here? what are the
undocumented or other wise strange behaviours with using 'usr'? (one is
for example that argument and return value should be of the same type)
