Re: FW: update files

[boothm@xxxxxxxxxxxxxxxxx]

Is there any way of knowing how "not very efficient" this choice is?  I 
know that when I use UP and take off the K in the file spec these programs 
are stunningly fast.

Does Barbara have any info to share on UP to a sequential file vs. a 
roll-your-own-cycle job?

FMyFile   UP   E               DISK

C             If           DType = 'JRNL' And DDStat = 'A'
C             Eval       DDstat = 'X'
C             Update  MyFile01

Assuming: file name is MyFile and record layout is MyFile01
That will do it for you.  This will read through every record in
MyFile and update as per your specs.  This is not very efficient,
however, as it does have to read through every record.  It does
this because the file is opened as the Primary file, and uses the
RPG cycle.
