now some records in $3 contain zeroes. i don't want to remove those records. is it possible to check for division by zero and then write a "N/A" for that record in the o/p file (in this case test)?
thanks
how can i show the value when i divide a number where the dividend is greater then the divisor. for example...
3 divided by 15 ---> let x=3/15
when i do this in the shell environment it gives me an output of 0.
please help me.
thanks. (3 Replies)

tcfmttest - test cases of the fixed-length database API
DESCRIPTION
The command `tcfmttest' is a utility for facility test under multi-thread situation. This command is used in the following format. `path'
specifies the path of a database file. `tnum' specifies the number of running threads. `rnum' specifies the number of iterations.
`width' specifies the width of the value of each record. `limsiz' specifies the limit size of the database file.
tcfmttest write [-nl|-nb] [-rnd] path tnum rnum [width [limsiz]]
Store records with keys of 8 bytes. They change as `00000001', `00000002'...
tcfmttest read [-nl|-nb] [-wb] [-rnd] path tnum
Retrieve all records of the database above.
tcfmttest remove [-nl|-nb] [-rnd] path tnum
Remove all records of the database above.
tcfmttest wicked [-nl|-nb] [-nc] path tnum rnum
Perform updating operations selected at random.
tcfmttest typical [-nl|-nb] [-nc] [-rr num] path tnum rnum [width [limsiz]]
Perform typical operations selected at random.
Options feature the following.
-nl : enable the option `FDBNOLCK'.
-nb : enable the option `FDBLCKNB'.
-rnd : select keys at random.
-wb : use the function `tcfdbget4' instead of `tcfdbget2'.
-nc : omit the comparison test.
-rr num : specifiy the ratio of reading operation by percentage.
This command returns 0 on success, another on failure.
