JCLCM0094I Non-JCL record in the input stream has caused this SYSIN DD statement to be generated.

This message, while it never appears in any JCL listings, is referred to in the generated SYSIN DD statement. It means that in your JCL source stream, you have one or more non-JCL records before the final // if any.

Example of non-JCL records

//MYJOB JOB 
//STEP1 EXEC PGM=IEFBR14
//SYSOUT DD SYSOUT=*
   some data
   some more data
//SYSPRINT DD SYSOUT=*
blank line
//

The above JCL will cause two statements of the form:

//SYSIN DD * ***MFE JCL GENERATED STMT*** For more info, see JCLCM0094I

to appear, one after /SYSOUT DD and the other after //SYSPRINT DD.

Note: One or more non-JCL statements preceding the first STEP also generate a JCLCM0642U error.
