Problem Note 33088: PROC NLIN may report invalid coding error and invalid sequence of command errors
 |  |  |  |
When using PROC NLIN under the following four conditions:
- PDATA= data set
- BY statement
- OUTPUT statement
- Variables exist in the input data set that are not used in the analysis
then the SAS LOG will report the following errors:
ERROR: INTERNAL CODING ERROR Attempt to define a new variable number 2 on file WORK.NEW.DATA. Xvfind()or xvname() has been called for an undefined variable after variable selection had been terminated via xvsele(). ERROR: Invalid sequence of commands for file WORK.PREDICTOUT.DATA.
To prevent this problem from occurring, drop all variables not used in the analysis using the drop sub-option on the DATA= option in the PROC NLIN statement:
data=yourdata(drop=variable1 variable2 variable3)
Dropping the unused varaibles allows the use of the PDATA= option, BY-group processing, and the OUTPUT statement.
