[fpc-pascal]absolute identifier

[ron wilson]

you are correct.  the type cast works very well.

in my case, however, i do need the setlength, because i don't clear the
buffer when i re-use it, i just set buflen:=0. so i have to set the length
if the buffer has garbage data beyond the current buflen.

Yes, it should and you don't need the setlength because the type
cast code does the job for you.
