Is there a way to stop IML exit when it gets errors? That's because I have to re-run everything again in IML after it exits.
It is possible IML exits when it encounters a certain number of errors, so perhaps I can limit this number.
See the following log of my program:
90 create mydata from tt01[colname=namevar];
ERROR: Matrix tt01 has not been set to a value.
statement : CREATE at line 90 column 1
91 append from tt01;
ERROR: No data set is currently open for output.
statement : APPEND at line 91 column 1
92 close mydata;
NOTE: Cannot close WORK.MYDATA; it is not open.
93
94 create mydata from ta01[colname=namevar];
ERROR: Operand namevar does not have a value.
statement : CREATE at line 94 column 1
NOTE: Exiting IML.
NOTE: Storage library SASUSER.MYMODULES closed.
NOTE: The SAS System stopped processing this step because of errors.
NOTE: PROCEDURE IML used (Total process time):
real time 26:06.64
cpu time 25.25 seconds

Wow. I never knew SAS/IML did that. How many errors are there? Is there a reason why you don't or can't fix the errors?
For unititialized variables, perhaps you could try something like:
if ncol(tt01)=0 then stop;
Another option:
if ncol(tt01)=0 then store _all_; /* save matrices in case IML exits */
I don't know if any of these will work. I know that there are a lot of system options that SAS supports for handling errors. See if the options on this page are useful: SAS(R) 9.2 Language Reference: Concepts, Second Edition
