I can use proc iml to submit sas code as long as I don't submit procs or datasteps. When I submit procs or datasteps the code doesn't run and my server connection is disconnected.    For example this runs: *Here I run some simple SAS code with outputs to the log; %put &=SYSSCPL; data _null_; put "hello"; run; *Here I submit the same SAS code using proc iml; proc iml; submit; %put &=SYSSCPL; %put "hello"; *If I uncomment the code below the overall program will not run and the server loses connection. This happens for any datastep or proc.; *data _null_; *put "hello"; *run; endsubmit; quit; The log looks like this: The SAS System 1 ;*';*";*/;quit;run; 2 OPTIONS PAGENO=MIN; 3 %LET _CLIENTTASKLABEL='Simple_IML_SAS_call.sas'; 4 %LET _CLIENTPROCESSFLOWNAME='Standalone Not In Project'; 5 %LET _CLIENTPROJECTPATH=''; 6 %LET _CLIENTPROJECTPATHHOST=''; 7 %LET _CLIENTPROJECTNAME=''; 8 %LET _SASPROGRAMFILE='I've removed this" 9 %LET _SASPROGRAMFILEHOST='I've removed this"; 10 11 ODS _ALL_ CLOSE; 12 OPTIONS DEV=SVG; 13 GOPTIONS XPIXELS=0 YPIXELS=0; 14 %macro HTML5AccessibleGraphSupported; 15 %if %_SAS_VERCOMP_FV(9,4,4, 0,0,0) >= 0 %then ACCESSIBLE_GRAPH; 16 %mend; 17 FILENAME EGHTML TEMP; 18 ODS HTML5(ID=EGHTML) FILE=EGHTML 19 OPTIONS(BITMAP_MODE='INLINE') 20 %HTML5AccessibleGraphSupported MPRINT(HTML5ACCESSIBLEGRAPHSUPPORTED): ACCESSIBLE_GRAPH 21 ENCODING='utf-8' 22 STYLE=HTMLBlue 23 NOGTITLE 24 NOGFOOTNOTE 25 GPATH=&sasworklocation 26 ; NOTE: Writing HTML5(EGHTML) Body file: EGHTML 27 28 /* Insert custom code before submitted code here */ 29 %_eg_autoexec; MPRINT(_EG_AUTOEXEC): options nomprint nosymbolgen NOTE: PROCEDURE PRINTTO used (Total process time): real time 0.00 seconds cpu time 0.00 seconds NOTE: The infile 'I've removed this" is: Filename='I've removed this", RECFM=V,LRECL=32767,File Size (bytes)=1944, Last Modified=23Apr2024:11:00:01, Create Time=23Apr2024:10:47:14 NOTE: PROCEDURE PRINTTO used (Total process time): real time 0.00 seconds cpu time 0.00 seconds NOTE: _EG_IncBiosetup did not run because [&root] already exists.

For example this works: proc iml; call ExportDataSetToR("Sashelp.Class", "df" ); submit / R; names(df) endsubmit; quit; I am using sas enterprise guide version 8.2 Update 5 (8.2.5.1277) (64-bit).  Until recently I was able to submit sas code using proc iml just fine. My company installed a hotfix in March. Is it possible that the hotfix broke something or changed a setting so that I am no longer able to use proc iml to submit sas procs or datasteps?     ...
