1 UTILITY FUNTION 1 PROGRAMS: GETTING STARTED hapter SYS-ED/ OMPUTER EDUATION TEHNIQUES, IN.

2 Objectives You will learn: To identify the tasks which can be performed by the utility functions. Utility control statements. Rules of control statements and identifiers. SYS-ED \OMPUTER EDUATION TEHNIQUES, IN. (JL UTIL - 0.8) h 1: Page i

3 The utility programs can be used to perform the following tasks. 1 Performing Tasks with Utility Functions Task Options Primary Utility Add a password Alter in place a load module atalog a data set in an VOL hange data set organization logical record length ompare partitioned data sets IEBOMPR PDSEs IEBOMPR IEBOMPR ompress a partitioned data set ompress in place a partitioned data set onvert to partitioned data set An unloaded PDSE containing program objects can not be loaded into a PDS.

8 2 Utility ontrol Statements Utility control statements are used to identify a particular function to be performed by a utility program and, when required, to identify specific volumes or data sets to be processed. Utility control statements are usually included in the input stream. However, they may also be placed in a sequential data set, or in a member of a partitioned data set or PDSE. The data set must have fixed or fixed blocked records with a logical record length of 80. The control statements for the utility programs have the following standard format: label operation operand comments When included, a name must begin in the first position of the statement and must be followed by one or more blanks. label operation operand an contain from 1 to 8 alphanumeric characters. Identifies the type of control statement. It must be preceded and followed by one or more blanks. Made up of one or more keyword parameters, separated by commas. The operand field must be preceded and followed by one or more blanks. ommas, parentheses, and blanks can be used only as delimiting characters. omments an be written in a utility statement, but they must be separated from the last parameter of the operand field by one or more blanks. 2.1 ontinuing Utility ontrol Statements Utility control statements are coded on cards or as online input and are contained in columns 1 through 71. A statement that exceeds 71 characters must be continued on one or more additional records. A non blank character must be placed in column 72 to indicate continuation. The continued portion of the utility control statement must begin in column 16 of the following record. SYS-ED \OMPUTER EDUATION TEHNIQUES, IN. (JL UTIL - 0.8) h 1: Page 6
