Hello everybody,    I submitted the following code:  proc sort data=WORK.FAMA3CONDITION out=date (keep=date) nodupkey; by date; run; proc surveyselect data=WORK.date out=outbootdate /*we tell the input and output dataset name*/ seed=30459584 /*We specify a random seed*/ method=urs /*We specify the type of random sampling (simple random sampling with replacement here)*/ samprate=1 /*In order to get a sample of the same size as our original data set, equal to 1 to have 100% sample*/ outhits /*makes sure that it generates an output record every time it hits a given record, rather than only the first time*/ reps=1000; /*replicates the number of sample*/ run; data outbootdate_1; set outbootdate; link=00; run; data FAMA3CONDITION_1; set FAMA3CONDITION; link=00; run; proc sql ; create table new_boot as select a.*,b.* from outbootdate_1 as a left join FAMA3CONDITION_1 as b on a.link=b.link and a.date=b.date; quit; proc sort data=new_boot out= new_boot_1; by replicate id date; run; proc reg data=new_boot_1 outest=new_boot_2; model TRUEPERF = MKT SMB HML; by Replicate id; run;   And it delivers the following message in the log:  ERROR: The SAS System stopped processing this step because of insufficient memory. WARNING: The data set WORK.NEW_BOOT_2 may be incomplete. When this step was stopped there were 546738 observations and 11 variables.   I tried to add  options memsize=max;  in my code but I received a warning message telling me I had to modify SAS configuration file   I used then the code  proc options option = memsize; r run;  to obtain the path and modify the sasv9.cfg file I changed memsize from 2G to MAX and save the changes.    These are the info in the log about the memory:  Group=MEMORY SORTSIZE=1073741824      Specifies the amount of memory that is available to the SORT procedure. SUMSIZE=0      Specifies a limit on the amount of memory that is available for data summarization procedures when class variables are active. MAXMEMQUERY=0      Specifies the maximum amount of memory that  is allocated for procedures. MEMBLKSZ=16777216     Specifies the memory block size for Windows memory-based libraries. MEMMAXSZ=2147483648   Specifies the maximum amount of memory to  allocate for using memory-based libraries. LOADMEMSIZE=0 Specifies a suggested amount of memory that is needed for executable programs loaded by SAS. MEMSIZE=5866245120  Specifies the limit on the amount of virtual  memory that can be used during a SAS session. REALMEMSIZE=0 Specifies the amount of real memory SAS can  expect to allocate.   I launched again my code but once again I obtain the same error message.    Does some have a solution for me please?    Thanks a lot!!  ...
