With 4k bufsize and a rowlength a little over 2048 bytes causes this write_sas to hang?

This works
have<-have[1,1:200];

This hangs
have<-have[1,1:261]

I think you need to fix the the offset (around byte 35 chahe 2 to 3 - see my first post
None of Matt Shotwell's sample SAS datasets use the offset haven uses

%utl_submit_r64('
source("C:/Program Files/R/R-3.3.2/etc/Rprofile.site", echo=T);

Reproducible example that hangs;

library(haven)
have<-structure(list(A1="",A2="",A3="",A4="",X1=0,X2=0,X3=0,X4=0,X5=0,X6=0,
X7=0,X8=0,X9=0,X10=0,X11=0,X12=0,X13=0,X14=0,X15=0,X16=0,X17=0,X18=0,

Confirmed that this now gives an error message.

@rogerjdeangelis can you please use tempfile() when writing to disk? Most of us do not have a D: drive
