Help with variables

Help with variables

I use to write code with Dbase VI way back when. Problem is I have forgotten almost all that I learned.

I need help with a uniqe variable, maybe it can't be done. I have data on flight plans that I want to export out into a text file. The code is as follows.
    NUM = 0
    ?RTRIM(AC) + "," + TRIM(REG) + ","
    DO WHILE NUM = 0
        ??LTRIM(STR(CA1)) + "," + RTRIM(FR1)
        ??LRTIM(STR(CA2)) + "," + RTRIM(FR2)
        Num = 1
My problem is that there are 185 feilds. There are CA1 and CA2 up to CA30. The same with FR1 and FR2 and six more feilds named like that.  
My question is how can I use a variable or variables to replace the 1 & 2 & 3 in the CA1.
I hope this is clear enough
Thanks for any help.

RE: Help with variables

what is the criteria to export the data? are you pulling the data out of the table (the dbf file)?

to use name replacement, use the & sign.

for lnIndex = 1 to 30
  y = alltrim(str(lnIndex))
  ?? CA&y

**** that would print
value of the fields:

is to open the table, and use the [copy to] command...

Dbase IV does not know what "for lnIndex" is.
Did you give me code for Dbase IV?

RE: Help with variables


FOR xx = 1 TO 30
  yy = LTRIM(STR(xx))
  ?? EVALUATE("yy")

FOR/NEXT is a loop structure.

lnIndex is just the variable name to which the sequential numbers 1 to 30 are assigned in the loop.  In my example above I have substituted variable names xx and yy.
