CA-ACF2 predefined general resources. In some areas their designs are similar, and in other areas the designs are very different. With proper planning, and perhaps with specially skilled people to assist in certain areas, the migration can usually be accomplished in an orderly way. Understanding the higher-level issues and differences between the two products is an important starting point.
Information can be read from a data set to the data stack for serialized processing or to a list of variables for random processing. Information from the data stack or a list of variables can be written to a data set.
Using quotation marks prevents the possibility of the operands being substituted as variables. Operands for Reading from a Data Set: In either case, if you also specify a non-zero value for the linenum operand, EXECIO sets the current record number to the record number indicated by the linenum operand.
By default, when a file is opened, the current record number is set to the first record record 1. DISKR opens a data set for input if it is not already open and reads the specified number of lines from the data set and places them on the data stack.
If the STEM operand is specified, the lines are placed in a list of variables instead of on the data stack. While a data set is open for input, you cannot write information back to the same data set.
The data set is not automatically closed unless: Typically, you open a data set for update when you want to modify information in the data set. When a data set is closed and reopened as a result of specifying a record number earlier than the current record number, the file is open for: When linenum specifies a record number earlier than the current record number in an open data set, the data set must be closed and reopened to reposition the current record number at linenum.
When this situation occurs and the data set was not opened at the same task level as that of the executing exec, attempting to close the data set at a different task level results in an EXECIO error.
The linenum operand must not be used in this case. Specifying a value of zero 0 for linenum is equivalent to not specifying the linenum operand. Good programming practice, however, would be to explicitly close all data sets when finished with them.
OPEN opens the specified data set if it is not already open. To place information in compound variables, which allow for easy indexing, the var-name should end with a period. When var-name does not end with a period, the variable names are appended with numbers and can be accessed in a loop such as: To avoid confusion as to whether a residual stem variable value is meaningful, you may want to clear the entire stem variable prior to entering the EXECIO command.
To clear all compound variables whose names begin with that stem, you can either: Use the DROP instruction as follows, to set all possible compound variables whose names begin with that stem to their uninitialized values: Set all possible compound variables whose names begin with that stem to nulls as follows:Executive Director Executive Director Total SSRC Expenditures by Org Test Model SSRC Operating Budget - 2nd and 3rd Tabs Business Office Bus Ofc(Alloc on Expends) Total SSRC Expenditures by Org Test Model SSRC Operating Budget - 2nd and 3rd Tabs Services Desk Direct Alloc to Services Desk Schedule Test Model Statistical.

Since the lead security administrator is the only person who understands the ins and outs, he becomes an untraceable, self-supervising agent.
CA Allocate DASD Space and Placement 4 Dynamic storage management: For new allocations, CA Allocate can automatically substitute a value consistent with user-defined standards when a unit, volume, space request, blocksize, catalog disposition or expiration date is incorrectly specified.
