Is there an easy way to make a CL program step through the objects in an IFS directory?
I wrote some CL commands called OPENDIR, READDIR, REWINDDIR and CLOSEDIR that are intended for reading IFS directories from a CL program. Here's a sample of how you might use these to read all files that end in .CSV from the /home/klemscot directory of your IFS:
midrange.com
PGM
DCL VAR(&DIR) TYPE(*CHAR) LEN(4)
DCL VAR(&FILE) TYPE(*CHAR) LEN(640)
DCL VAR(&DONE) TYPE(*LGL) VALUE('0')
OPENDIR HANDLE(&DIR) DIR('/home/klemscot') REGEX('.*CSV$')
LOOP: READDIR HANDLE(&DIR) NAME(&FILE)
MONMSG MSGID(CPF0000) EXEC(CHGVAR VAR(&DONE) VALUE('1'))
IF (&DONE *EQ '0') DO
CPYFRMIMPF FROMSTMF(&FILE) TOFILE(MYLIB/MYFILE) RCDDLM(*CRLF)
RMVLNK OBJLNK(&FILE)
GOTO LOOP
ENDDO
CLOSEDIR HANDLE(&DIR)
ENDPGM
The REGEX parameter to OPENDIR is used to subset the results by a given
regular expression. (It's an optional parameter, you can omit it if you
don't need that capability.)
These CL Commands are written in a mixture of ILE CL and ILE RPG, but once you've installed them, you can call them from OPM CL as well without any worries.
These tools were written as part of an article I wrote for iSeriesNetwork.com. You can read the article and download the code from the following link (requires a Professional membership in the iSeries Network):
