Re: Subfile problem

Hi Booth
Is there any advantage on using a for loop over a do loop, or is it just
personal preference?
If there is an advantage, I am always willing to learn new things.

I like a for loop:

C             for    Subfilerrn = 1 to SflSiz
C  Subfilerrn chain  Subfile
C             if     Option = 'X'
C             exsr   ProcessData
C             endif
C             endfor

Where SflSize equals the size of the subfile (you probably have that as
a known number already).

Hi Phil

the following code should show you what is needed.

c                       eval        Subfilerrn = 0
c                       dou         not %found(Workstn)
c     Subfilern   chain       Subfile
c                       if          %found(Workstn)
c                       if          Option = 'X'
C           exsr  processdata
C           endif
c           enddo
Where Workstn is your worstation file name
subfile     is the subfile record
Subfilerrn is the rrn associated with that subfile (or any other

counter

Oops it worked now! But tell me anyways if you have a moment how you

do

this read. I have only done subfiles that displayed rows of data and
accepted the 'X' (or 2/4/5) next to the record the user could update.
Then I display another format w/ this record for them to change.  So

I

DID do a READC looking for this 'X'. thus, this way of changing data

on

the rows directly is new to me.

Thats why I stopped using READC.  Just too many headaches.  Read the
whole subfile.  The performance hit is minimal, if even noticeable.

The problem I am having is to reset the subfile. IOW, I have a

that checks each line via a READC, that is doing a  dow       not

But it is NOT going through and checking upon hitting enter, the
indicators are controlling. Because, EOF has been hit. I am not sure

how

to reset the subfile.

If I am understanding you correctly,

You should only have to reset the indicator for the line once the

error

has
been corrected.  On your "else", you need to update the subfile

record

there too because you are changing the value of *In60.

HI, I have a subfile program that when there is an error, on say

the

third line, on the first pass, the cursor is being put on the third

line

correctly, but subsequently, the cursor will be placed on the first
line. Let's say if I correct the third line but make an error on

first,

then correct the first and re-error on third, it then positions on
FIRST. I appear to be missing code that would correctly align the

cursor

to the error line, or perhaps I need to clear the subfile on each

ENTER?



The code is:



C     prolin       begsr

C                   readc     sfr1

*


  *

C                   dow       not %eof

 *

C                   if        s6sqty =  0

c

C                   eval      *in60 = *on

C                   eval      *in59 = *on



C                   eval      *in74 = *on

C                   update    sfr1

c                   else

C                   eval      *in60 = *off

c                   endif

C                   eval      *in74 = *off

c*

c                   readc     sfr1



C                   enddo

C                  endsr



Ind. 60 is to position the cursor:



A  60                                  DSPATR(PC)
