Hi All,
The Requirement is to List all the members in a PDS Dataset along with size of the MEMBERs. Is it possible in REXX. Please give some tips to built further. PDS contains 2000+ Members.
Tnx |

| What do you consider to represent the SIZE of a member? Number of lines? You can get all of this and more in ISPF. |

| An interesting question. The ISPF statistics of course include number of lines, as superk indicates, and the directory of a load library includes a SIZE (in bytes) field. I do not think, though, that there is a general method available through REXX of doing so, although you may not actually need a highly generalized method. What sort of PDS is it? |

As you said and superk said, if the PDS contains normal data or some jcl it is possible to check the no. of line count and get the info. but my req. is for LOAD members. Some members contains 2 to 3 lines only but size is 20 bytes. So I am not able to get...  |

Hello,
Suggest you post part of the browse directory list (from tso/ispf 3.4).
I suspect you are not yet familiar with the info presented. |

Do you mean 20k or something, or actually 20 bytes. If actually 20 bytes, it is not a load module.
In addition to the PDS information Dick is drawing your attention to, which does have the size of the load module (the "size"), AMBLIST reports on modules, including "LENGTH OF MODULE". There is a lot of additional information, but if you have a bit of rexx (or whatever) to process the output listing from AMBLIST, when you happen sometime in the future to need to know something else that is on the report, you'll be 90% of the way there already. |

Here in code AAAAAAA member the no. of lines is 15 and size is 2278, I want to capture this member list along with size for 6000+ member(find at top). And I started coding REXX from 25th Sep so i am new to REXX functions and new concepts. If u suggest some sites to get knowledge hope that is ok to start writing for req.
Thanks to dick scherrer & Bill Woodger |

Hello,
In the member you mention, the length is 2278 (in Hex). In decimal this is 8824.
The number of lines is not the length. |

Hi Bill,
As you said I used AMBLIST keyword and get the jcl and submitted it shows lot of info including the size. now i will get the length thro REXX. Thank u thank u......
| Code: |
//AMBLISTS JOB 'UMAS',CLASS=A,MSGCLASS=X,MSGLEVEL=(1,1),
// REGION=0M,NOTIFY=&SYSUID
//* SHOW LOAD MODULE ATTRIBUTES
//AMBLIST EXEC PGM=AMBLIST
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
LISTLOAD DDN=SYSLMOD
/*
//SYSLMOD DD DSN=XXXX.EEEEE.LOAD,DISP=SHR |

Where did you get the number of lines? Load module datasets should have a record format of U (unformatted). That is, there are not any lines. |

Uma Sankar, begin with this. If it is unclear, we will talk further.
| Code: |
/* Rexx */
/*********************************************************************/
/* */
/* This routine incorporates ideas and algorithms by Doug Nadel. */
/* */
/*********************************************************************/
trace o
x = msg("OFF")
arg pds
y = LISTDSI("'" || pds || "'")
if (y¬=0) then
return 8
if (substr(sysdsorg,1,2)¬="PO") then
return 12
"ALLOC DA('" || pds || "') FI(TULUT1) SHR LRECL(256) RECFM(F B) DSORG(PS)"
"EXECIO * DISKR TULUT1 (FINIS STEM ENTRY."
"FREE FI(TULUT1)"
do i = 1 to entry.0
/* the first two bytes are the logical record length */
parse var entry.i entryl 3 entry.i
entry.i = substr(entry.i,1,c2d(entryl)-2)
do while (entry.i¬='')
parse var entry.i member 9 ttr 12 pds2indc 13 . 23 length 26 entry.i
b = x2b(c2x(pds2indc))
if (substr(b,1,1)='1') then do
parse var entry.i . 12 alias 20 entry.i
c = (x2d(b2x(substr(b,5))) * 2)
end
else do
alias = ''
c = (x2d(b2x(substr(b,4))) * 2) - 13
end
if (member='FFFFFFFFFFFFFFFF'x) then
leave i
ttr = c2x(ttr)
length = c2x(length)
say member "is" length "(hex) bytes long"
if (alias¬='') then member = alias
entry.i = delstr(entry.i,1,c)
end
end
return 0 |

I just checked IEFBR14 and the member list shows a size of 00000008, with:
| Code: |
********************************* Top of Data **********************************
.Ø......IEFBR14 ........
س..............................................................................
Ø..5695PMB01 ....|..ë.
Ø..Ø..566896201 ....¤
Ø.h......RSI53390780
............ .......
...Ú....
******************************** Bottom of Data ******************************** |
Now I am confused about what a size of '8' really means. Clearly there are more than 8 bytes in the member. Nor are there 8 blocks of data. |

the ISPF member list shows the SIZE of the <module> i.e what gets loaded and executed
the rest is binder/loader info needed for the proper <loading> and relocating of the executable in virtual storage
for example all the RLD ( Relocation and Linkage Directory ) needed to adjust the addresses of relocatable entries inside the load. |
