Re: READC, dou, and For

[Jason Olson <jolso@xxxxxxxxx>]

I always use READC.

I guess becasue normally I use a subfile to choose something. So why would
I want to read though each record when only one of them should be changed.

And even if there are more then one value selected I still use READC.



Thank you,

Subject:    READC, dou, and For


An interesting discussion came up the other day.  Leastways, it was
interesting to me.

To read through a subfile in olden days we could use READC and SFLNXTCHG.

Then it became a lot easier and just as fast to loop, reading every subfile
record, with a dou loop.

Then along came the FOR loop and I am hearing that we should use a FOR
loop,
from 1 to SFLRECS, where SFLRECS is the size of the subfile.

What are the thoughts of those here assembled?
