RE: Search for SELECT / FROM parameters in a CGI source from RPG

What I do is this,

I read 1024 bytes (note parameter 1 = fp which is the current position in
the file meaning, I read 1024 bytes from where I am).

I walk thru those 1024 bytes  in a loop like this;

C         EVAL IX        = IX + 1
C         EVAL CURCHAR   = %SUBST(Input: IX: 1)


Looking at each CURCHAR looking for a Carriage return, if it is, I write
out to my DB2 file a PF record (fixed record length, one field, character
data type.


C                   SELECT
C                   WHEN      CURCHAR    =  CR
C                   EVAL      DBField    =  LogicalRec
C                   WRITE     DBFormat
C                   EVAL      IX         =  *ZERO
C                   EVAL      LogicalRec =  *BLANKS

If not, I just add the CURCHAR to the DB2 field I am building.

C              EVAL      IX         =  IX  +  1
C                 EVAL      %Subst(LogicalRec: IX: 1) = CurChar

-------------------------------------------
Would you have this in a Do-Loop, to read each 1024 blocks of data?
Say something like...

C                DOU          Whatever
C                EVAL      CHARSREAD     = read(fp: %addr(input): 1024)
C                   IF        CHARSREAD    <=  0
C                   LEAVE
C                   ENDIF
C                ENDDO

Would this be accurate?  Will the read() know to pull the next 1024 each
time?
