Tricks of the Trade Reports

Casual CA Easytrieve users can use these reports as examples of coding techniques such as date/time conversions, indexed variables, and multiple passes at data.

CA Easytrieve Member Name

Report Name

SMF/EXT Record Type

Trick

EZXT0256

Cache Subsystem Status

74-5
R74B

Invokes macros that produce scaled numeric values. Scaling is useful for displaying very large numbers in a limited number of print positions. The sample report invokes UNSBINZ.

EZXT0314

Tape Library Volume Pool - Hourly Poolset Statistics

94-2
VTS2

Uses the CASE:WHEN construct in CA Easytrieve.

EZXT0320

TCP/IP Connection Termination

119-2
STCT

Uses an AFTER-BREAK PROC and the DISPLAY command to produce a two-line value (IPv6 address) to customize a summary report. Also illustrates the use of the IPV6CNVZ macro to convert 64-bit IPv6 values to standard printable format. IPV6CNVZ also contains an example of how to work with arrays in CA Easytrieve that is simpler and clearer than that in EZXTZ002.

EZXT0338

CPU Activity Daily Report

70-1
70C, R70P

Uses multiple VIRTUAL files to manipulate data in multiple passes.

EZXT0340

ESS Link Statistics

74-8
RSSL

Invokes macros that produce scaled numeric values. Scaling is useful for displaying very large numbers in a limited number of print positions. The sample report invokes ESSLSCLZ.

EZXT0348

I/O Queuing - Logical Control Units

78-3
R78B

Uses a memory array to compute multiple statistics on a variable in a single pass. Uses report procedures REPORT-INPUT and BEFORE-BREAK.

EZXT0349

I/O Queuing - Channel Paths

78-3
R78C

Uses the CA Easytrieve automatic variable TALLY.

EZXTZ002

Session Detail Stats

zVM accounting record 1
SIEZ

Uses a STATIC variable in CA Easytrieve to access an array of values in a REPORT procedure. Uses an AFTER-LINE PROC to do complex arithmetic in a REPORT procedure. Illustrates the use of indexed variables.

EZXTZ004

VM Special Processor Use

zVM accounting record 1
SIEZ

Uses a REPORT-INPUT PROC to do complex record selection in a REPORT procedure.
