CA File Master Plus for batch provides the following data manipulation functions:

• Data sets supported are:
  • VSAM data sets: KSDS, ESDS, RRDS (fixed and variable), and linear data sets
  • Sequential and partitioned data sets
• With COMPARE, differences between two files can be identified as follows:
  • Restrict your comparison to as few as comparing one byte or to the entire record
  • Compare different locations between the two files
  • Exclude or include records from the compare using selection criteria, IF, SELRECIF, and SKIPRECIF
  • Print your data and differences in an easily readable format with the use of the LAYOUTFILE keyword
  • Write the CHANGED, DELETED, INSERTED, and MATCHED records of both the old or new files to their separate files.
• COPY provides a method for duplicating, extracting, reformatting, and updating your data. Data manipulation that can be done includes the following:
  • CA File Master Plus supports copying data to and from differing file formats, including copying a VSAM or PDS file to a sequential file
  • Selection criteria used in conjunction with the MOVE and WRITE command keywords allow you to pinpoint and extract data
  • COPY also lets you reformat the data
  • The REFFILE keyword lets you rearrange or delete existing fields and insert new ones
  • Using the keywords, REPLACE, EDIT, and CHANGE allows updates to your data while you copy it
• The LOADINFO function produces a detailed load module report listing each load module's attributes, or you can generate a CSECT cross-reference report.
• The PRINT function is a powerful utility that formats and prints data in easily readable formats. This command allows you to perform the following functions:
  • Format data according to your COBOL, PL/I, or custom copybook, including the ability to select different copybooks when processing the same file based on a record's data
  • Minimize the data printed by excluding unwanted data from the printout using the PRINT command with the COMPREPORT, FIELDDISPLAY keyword or by using your selection criteria
  • Specify the format of the data's printed output (for example, in hexadecimal or character formats) with the FORMAT keyword
• PRINTLOG is a utility that formats and prints the information contained in the editor's change log file. The change log file tracks the changes made to a file during a CA File Master Plus edit session.
• When the READ command is used with selection criteria and the MOVE and WRITE keywords, you can identify specific records and write them to a new file. Advantages of using the READ command with selection criteria are as follows:
  • Lets you create many output files while only reading the input file once
  • Create a new file with only specific data from the input record
  • Not necessary to copy the entire input record to a new file
  • Using single or multiple ACCUM keywords, READ permits addition of single or multiple numeric fields for all records or only for selected records and print those totals at the end of the report
• UPDATE delivers a method to change data in the file such as:
  • Bypassing changes depending on your particular selection criteria
  • Selection criteria can query the record's data or a simple character string before making any update
  • Updates are made immediately to the input file
• CA File Master Plus also provides the ability to display DSN and VOLSER VTOC information such as:
  • DSNINFO lets you examine DSN entries on one or more volumes
  • VOLINFO provides volume summary data about one or more volumes or unit types. This information includes how much free space is on the volumes, the device type, and even the largest contiguous space available. Use VOLINFO with the MAP keyword to generate a detailed extent map for the VOLSER or UNIT keyword values.
• COBOL and PL/I copybook support.
  • Printing a record's data overlaid with a copybook is considered formatted print. The data is printed in the format as defined by the copybook, unless the data is invalid for the defined format, in which case the field's data is printed in hex. There are two flavors of formatted print, single record and multi record formats. Single record places the field name along the left side of the display, whereas multi record uses the field names as column headings.
• Scan mode is used for verifying the validity of control statements.
  • Control statements are not executed when in scan mode
  • Scan mode can easily be turned on or off by including or excluding the PARM JCL parameter
