Mainframe JCL and EZTrieve Functions

SKIPREC=n in SORT control statements causes DFSORT to skip n records at the beginning of processing before it starts sorting or merging. This happens before the actual sort/merge operations begin. The statement says skip process starts before processing n records, which is essentially correct - skipping occurs before the main processing.

TYPRUN=SCAN is a JES parameter that causes JES to scan the job's JCL for syntax errors without executing the job. This is useful for validating JCL syntax before actual execution. The statement correctly describes this functionality.

The PRTY (priority) parameter in JCL assigns a selection priority to a job within its job class in JES2, or within a job class group in JES3. This priority influences when the job is selected for execution relative to other jobs in the same class or group. The statement correctly describes the PRTY parameter's purpose.

The COND parameter COND=(4,GT) means the step will execute if the return code of a previous step is NOT greater than 4. If the first step gives RC=8, then 8 is greater than 4, so the condition evaluates to true and subsequent steps will be bypassed, not executed.

A JCL (Job Control Language) stream must begin with a valid JOB statement containing a Jobname. The Jobname is not optional; it identifies the job to the operating system's Job Entry Subsystem (JES). Therefore, the statement is false.

The // delimiter at the start of a line marks the end of JCL input for a job. This tells the system that there are no more JCL statements for this job. The statement correctly identifies // as the JCL terminator.

COND=ONLY is a special condition parameter that causes a step to execute ONLY if a previous step in the job abended (abnormally terminated). This is different from normal COND logic which skips steps based on conditions. The statement correctly describes COND=ONLY behavior.

Keyword functions in this system are enclosed within pipe symbols (|) to clearly mark their boundaries. The |EZCYMFP4| and |EZMSDSY| notation in other questions shows how function codes are placed between pipe symbols, making C the correct answer.

The system limits keyword functions to a maximum of 63 characters. This is a common technical constraint in many systems that ensures manageable function names and prevents excessively long identifiers.

Coded keywords are not converted immediately before job submission. The conversion happens at a different stage in the workflow, allowing for proper validation and processing before the final submission step.

Keyword functions are evaluated from left to right, following standard reading direction. This means the leftmost function in a sequence is processed first, then evaluation proceeds sequentially through remaining functions.

Keyword parameters do not support retrieving future or past date values. The system likely only provides current date-related values through these keywords, not relative date calculations or offsets.

The dollar sign ($) is used as a validation symbol to ensure a valid date is returned. This symbol acts as a flag that triggers date validation checks when processing date-related keyword functions.

The keyword function |EZCYMFP4| returns 201007 when the job runs in November 2010. This appears to calculate a specific month offset, returning July 2010 in YYYYMM format for reporting or fiscal period purposes.

The keyword function |EZMSDSY| returns the date in MM/DD/YY format, using forward slashes as separators. This is a common American date format with month first, then day, then two-digit year.

The keyword function |EZN| returns the full month name in uppercase. When the job runs in March, it returns 'MARCH' rather than the abbreviated form 'MAR' or numeric representation '3'.

The system limits keyword functions to a maximum of 63 characters. This is a common technical constraint in many systems that ensures manageable function names and prevents excessively long identifiers.
