A small example program and prj file are attached.
I think the IDynStr interface rates up there with Super Crunchy Peanut
Butter on pancakes, too bad there is not any documentation.

Project file follows at the end of the code:
teststr.clw:
program
include('dynstr.inc'),once
map
ShowCStr(*cstring)
ShowStr(string s)
main()
end
DynQ queue
dStr &IDynStr
end
x long
strVar string(50)
holder &cstring
code
main()
return
main procedure()
code
strVar = 'This is another string'
DynQ.dStr &= NewDynStr()
add(DynQ)
DynQ.dStr &= NewDynStr()
add(DynQ)
get(dynQ, 1)
dynQ.dStr.cat('This is the first string')
get(dynq, 2)
dynQ.dStr.cat(strVar)
loop x = 1 to records(dynq)
get(dynq, x)
message('just show the string in a loop ||' & dynq.dstr.str())
end
get(dynq, 1)
ShowStr(DynQ.dStr.CStr())
get(dynq, 2)
ShowStr(DynQ.dStr.CStr())
get(dynq, 1)
ShowCStr(DynQ.dStr.CStr())
get(dynq, 2)
ShowCStr(DynQ.dStr.CStr())
get(dynq, 1)
DisposeDynStr(dynq.dStr)
get(dynq, 2)
DisposeDynStr(dynq.dStr)
free(dynq)
return
ShowCStr procedure(*cstring s)
code
message('inside procedure with a *cstring parameter || ' & s)
return
ShowStr procedure(string s)
code
message('inside procedure with a string parameter || ' & s)
return
-- teststr
