1A1. Easytrieve Conversion - Overview

Easytrieve conversion to 'uvcopy'

'ez2uvcopy' is a Vancouver Utility (from UV Software) to convert CA Easytrieve to the uvcopy interpretive language. 'uvcopy' is a powerful data manipulation language that was developed to replace various mainframe utilities when converting to Unix or Linux systems.

uvcopy provides functions that are non-existent in the usual Unix utilities:

uvcopy is somewhat similar to the IBM 360 assembler language, so if you have a mainframe background the code will look familiar to you. In addition to the usual basic instructions, uvcopy has many powerful instructions for scan/replace, table processing, etc.

uvcopy has the power of assembler but without the complexity of compiling since it is 'interpretive' (just edit the parameter file & rerun).

There is a lot of documentation for uvcopy, but if you have a mainframe background, I think you could get a quick start by studying the examples given in UVjobs1.htm. Then you could run the 'eztlist1' conversion given in Part 1 of this EZTRVetc.doc & refer to the uvcopy3.htm instruction manual as required.

1C1. Easytrieve conversion to Vancouver Utilities

Easytrieve conversions - Pre-Requisites

Easytrieve conversions will probably be performed following the JCL conversions (documented in JCLcnv1demo.htm &/or VSEJCL.htm).

JCLcnv1demo.htm#Part_3 instructed you to setup user 'mvstest' (/home/mvstest), copy supplied demo files from /home/uvadm/mvstest/..., run the conversions,& execute the resulting Korn shell scripts.

If you did the above, you are ready to begin the Easytrieve conversions, because mvstest includes the directories & files required for the easytrieve test/demos.

If you have not already setup 'mvstest', the following instructions will show you how to setup 'testlibs' & 'testdata' in your homedir, copy the demo files, run the conversions,& execute the resulting uvcopy jobs.

The following instructions will assume your userid is 'userxx'.

Pre-Requisite for test/demos

You must setup your profile to use the Vancouver utilities as instructed in admjobs.htm#Part_1.

Converting Easytrieve - 1 program at a time

The following Operating Instructions are based on the supplied demo 'eztlist1' which was listed on page '1B1' & the expected converter output on page '1B2'.


 #1. Login userxx ---> /home/userxx

 #2. cdl   <-- change into libraries using alias 'cdl' (in common_profile)
     ===       alias cdl='cd $RUNLIBS' & RUNLIBS=$HOME/testlibs

 #3. uvcopy cleanup,fili1=ezt0/eztlist1,filo1=ezt1/eztlist1,uop=q0i7g8n1
     ===================================================================
     - cleanup mainframe easytrieve source (clear cols 73-80)

 #4. uvcopy ez2uvcopy,fili1=ezt1/eztlist1,filo1=ezt2/eztlist1
     ========================================================
     - convert mainframe easytrieve source to uvcopy code

 #5. cp ezt2/eztlist1 ezts
     =====================
     - copy to ezts before any changes that may be required
     - protects overwriting your edits in case of conversion reruns
Note
  • see page '1E1' to Execute the converted easytrieve (uvcopy job)

1D2. Easytrieve conversion to Vancouver Utilities

Converting Easytrieve - ALL programs in directory

The operating instructions to convert ALL files in a directory are actually easier than for 1 file at a time, because we only need to specify the directory names (vs individual files).

Note that 'uvcopy' is replaced by 'uvcopyx' which is a script that repeats the specified uvcopy job (cleanup or ez2uvcopy) for all files in the directory.


 #1. Login userxx ---> /home/userxx

 #2. cdl   <-- change into libraries using alias 'cdl' (in common_profile)
     ===       alias cdl='cd $RUNLIBS' & RUNLIBS=$HOME/testlibs

 #3. uvcopyx cleanup ezt0 ezt1 uop=q0i7g8n1
     ======================================
     - cleanup mainframe easytrieve sources (clear cols 73-80)

 #4. uvcopyx ez2uvcopy ezt1 ezt2 uop=q0i7
     ====================================
     - convert mainframe easytrieve sources to uvcopy jobs

 #5. cp ezt2/* ezts  <-- do NOT do this
     ==============
Note
  • NEVER copy ALL converted jobs (ezt2/*) to the execution directory
  • we will copy 1 at a time when we are ready to test/debug each job
  • this protects overwriting your edits when mass conversions are rerun
  • 'ezts' holds only the jobs that are already tested or in debug

 #5a. cp ezt2/eztlist1 ezts
      =====================
      - copy 1 at a time only when we ready to edit/test/debug each job
      - protects overwriting your edits in case of conversion reruns

1D3. Easytrieve conversion to Vancouver Utilities

possible manual changes after auto-conversion

After automatic conversion by 'ez2uvcopy', many jobs will execute with no manual changes, but some may require changes. Here are the possible changes we are aware of & some of these may be automated in future.

  1. insert record-size on fili1=...,etc if FB(...) not coded on FILE stmtns - 'rcs=99999' is coded if the record-size cannot be found

  2. change default file 'typ=RSF' ('FB'in mainframe Easytrieve) if required - 'typ=LSTt' for output report files (to insert LineFeeds) typ=LSTt is coded autoamtically if 'SYSLST' was coded on the FILE - 'typ=ISF' if Indexed Sequential keyed file

  3. change Packed fields to unpacked if used for DISPLAY msgs

  4. 'SORT' statements are #commented out - can code manually, see http://www.uvsoftware.ca/uvcopy3.htm#sort - or could code a preceding 'uvsort' in the script that calls easytrieve

  5. 'REPORT' writer not converted automatically - can code equivalent instructions manually - or use 'uvqrpg' (VU report writer) vs 'uvcopy' default

  6. Some statements not fully converted, but easy to fix manually, for example:
    IF FIELDA EQ 'A', 'B', 'C'   <-- easytrieve
    cmc $fielda,'A'              <-- auto conversion to uvcopy
    tst $fields,'ABC'            <-- manual correction
  1. Most programs have 'GO TO JOB' at end of the input file coding - if not the converter automatically generates - but could be fooled if some prior conditional 'GO TO JOB' exist

  2. MACRO's require manual change, often used for record definitions %custmas <-- easytrieve macro (record def from library) lod=qq0(48),custmas <-- uvcopy equivalent (library def fild7=...)

  3. Some special symbols may not be recognized, for example: IF EOF FILEA <-- easytrieve cmc a0(4),'EOF~' <-- uvcopy equivalent
