text: Constructing a CEEUOPT CSECT is documented in*z/OS Language Environment*
  *Customization,*SA22-7564. A sample CEEUOPT CSECT is included in dataset 
  CEE.SCEESAMP(CEEUOPT). You can use this sample as a model, but you must ensure that 
  the following option is specified: 
  
  RTEREUS=(ON) 
  
  CEEUOPT CSECT must be assembled and link-edited with the COBOL object code. In 
  addition, you must ensure that the resulting module is link-edited as NOT RE-ENTRANT and 
  NOT REUSEABLE. This task is required for the local variables within the COBOL exit code to 
  retain their values. This exit is invoked several times during an ACIF run. The sample source 
  code is in the SARSINST library member ARSSPVIN. Example 11-15 shows a sample 
  CEEUOPT CSECT.
