Hi,
I have a requirement to code in REXX. My Input file looks like below.
MODULEA RGN1
MODULEB RGN1
MODULEC RGN3
MODULEA RGN2
MODULEA RGN3
MODULEB RGN4
MODULEA RGN5
MODULEC RGN6
I wanted to remove the record from the file, where the module name occurs for the second time. My output should look like this.
MODULEA RGN1
MODULEB RGN1
MODULEC RGN3
Please provide me the code in REXX to this activity. |

I realize that it is not REXX, but instead a CLIST, and it excludes the dups
| Code: |
ISREDIT MACRO
CONTROL NOLIST NOCONLIST NOSYMLIST NOPROMPT NOMSG NOFLUSH ASIS END(ENDO)
ISREDIT RESET
ISREDIT (NUMLNS) = LINENUM .ZL
ISREDIT (CURLN) = LINENUM .ZF
SET LASTLN = &STR()
SET THISLN = &STR()
SET &STCOL = 1
SET &ENDCOL = 40
DO WHILE &CURLN < &NUMLNS + 1
ISREDIT (THISLN) = LINE &CURLN
SET THISLN = &SUBSTR(&STCOL:&ENDCOL,&THISLN)
IF &STR(&THISLN) = &STR(&LASTLN) THEN +
DO
ISREDIT CURSOR = &CURLN
ISREDIT EXCLUDE ALL .ZCSR .ZCSR
ENDO
SET LASTLN = &STR(&THISLN)
SET LSTLN = &CURLN
SET CURLN = &CURLN + 1
ENDO
EXIT
|
a quick attempt to convert to rexx is as follows:
| Code: |
/* REXX */
ISREDIT MACRO
ISREDIT RESET
ISREDIT (NUMLNS) = LINENUM .ZL
ISREDIT (CURLN) = LINENUM .ZF
LASTLN = ""
THISLN = ""
STCOL = 1 /* change the start col and endcol */
ENDCOL = 40 /* depending on your need */
/* or simply enter the start col and end column */
/* as arguments */
/* */
DO WHILE CURLN < NUMLNS + 1
ISREDIT (THISLN) = LINE CURLN
THISLN = SUBSTR(THISLN,STCOL,ENDCOL)
IF THISLN = LASTLN THEN +
DO
ISREDIT CURSOR = CURLN
ISREDIT EXCLUDE ALL .ZCSR .ZCSR
END
LASTLN = THISLN
LSTLN = CURLN
CURLN = CURLN + 1
END
EXIT
|
at the end of the rexx you can type in DELETE ALL X
or you can put the command in the REXX macro. |

Note that if it is a large dataset, an Edit-Macro won't do the job.
I recommend invoking SORT from within REXX - much faster & possibly less error-exposed.

Ditto, also if the dataset is on tape and the REXX runs in foreground.

Hello,

Someone "who must be obeyed" may have dictated that rexx be used, but there is no business requirement to use rexx. . .
The business requirement is to deal with the duplicates.
Whichever is a proper tool should be used. . .
Sounds like once again, someone has found a neat little hammer (rexx) and wants everything to be done to be a nail . . . |
