JCL JCLLIB Statement

Code Example

## JCL JCLLIB Statement

The JCLLIB statement specifies libraries to search for procedures and include members.

### Syntax
\`\`\`jcl
//name JCLLIB ORDER=(library1,library2,...)
\`\`\`

### Placement Rules
- Must appear after JOB statement
- Must appear before first EXEC statement
- Only one JCLLIB per job

### Search Order
1. Libraries in JCLLIB ORDER
2. System PROCLIB (installation defined)

### Maximum Libraries
Up to 15 libraries can be specified.

### Use Cases
1. Custom procedure libraries
2. Project-specific JCL includes
3. Test vs production procedures
4. Site-specific overrides

### INCLUDE Statement
JCLLIB also affects INCLUDE searches:
\`\`\`jcl
//JCLLIB ORDER=(MY.JCL.LIB)
// INCLUDE MEMBER=COMMONDD
\`\`\`

### Best Practices
- Use consistent library naming
- Test libraries before production
- Document library purposes
- Keep libraries organized
