This is likely more a philosophical question. I am writing a CGI in
REXX. One thing this program needs to do is read a number of files in a
specific subdirectory. My current approach is to use "pure" REXX code to
do this. This means reading the entire directory (using "address syscall
readdir") to get a list of the files in the subdirectory into a stem
variable. I am then using an "address syscall readfile" in a loop to
read the contents of the each file. Each file has a single record in it.
I am then searching the second field in that record to see if it
contains a specific string, entered by the user via a Web page. The
fields in each record are separated by tab ('05'x) characters.
Altogether, omitting the error checking, this takes about 15 lines of
REXX code.However, I have alternate method. The REXX program uses BPXWUNIX to run an "awk" program to do the search. The "awk" program is only 4 lines long. The plus of this is that it is much shorter. The minuses are that: (1) it uses BPXWUNIX to fork/exec an awk program; (2) it uses "awk" which nobody else on my team is familiar with. So, should I go with the longer pure REXX program which is possibly more understandable? Or should I go with the REXX/awk hybrid which is, in some ways, simpler but has more overhead? This is likely going to be a low use program. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
