     Posted: 17 May 2011 at 10:46am
I'm trying to convert a date formatted as a number 20110105 to 01/05/2011, but I receive a message "String is Non Numeric", any suggestions?
 
if not ISNULL({Command.MLIDDT})then DATE(CDBL(LEFT(CSTR({Command.MLIDDT},0,""),4)),if not ISNULL({Command.MLIDDT})then  CDBL(MID(CSTR({Command.MLIDDT},0,""),5,2)), if not ISNULL({Command.MLIDDT})then CDBL(RIGHT(CSTR({Command.MLIDDT},0,""),2)))

how about the simple approach:
 
local stringvar d := {table.field};
if not isnull(d) then
  DATE(mid(d,5,2)+"/"+mid(d,7,2) + "/" + left(d,4))

HTH, thanks for the response.    Here's what I have, I receive message A String is required here, {Command.MLIDDT} when declare the variable.  
 
 local stringvar d := {Command.MLIDDT};
if not isnull({Command.MLIDDT}) then
  DATE(mid(d,5,2)+"/"+mid(d,7,2) + "/" + left(d,4))  DATE(mid(d,5,2)+"/"+mid(d,7,2) + "/" + left(d,4))
 
I changed to:
local numbervar d := {Command.MLIDDT};
if not isnull({Command.MLIDDT}) then
  DATE(mid(d,5,2)+"/"+mid(d,7,2) + "/" + left(d,4))
 
Then receive message 'A String is required here'  for  'd'  in DATE(mid(d,5,2)+"/"+mid(d,7,2) + "/" + left(d,4)).
 
any help is appreciated.

What sort of field is the MLIDDT field?  I was assuming that it was a string.
 
I would try d:= toText({table.field}, 0, "").  If CR thinks it is a number, this will format it without a decimal or trailing zeros.
 
if it is not a number, I would just try a generic toText()...and to see what CR is converting it to, I would create a simple fomula like:
 
toText({table.field}) and dropping it on the report where appropriate.  From there you will probably be able to determine how to tell CR to format it so that you get the string that you are after.

HTH - I figured it out.
 
The formula didn't like when MLIDDT field contained a '0' instaed of a real date. I think this cuased the formula to attempt to pass an empty string as 'month' parameter for the DATE() function, which is when it was expecting a numeric value.
 
if not ISNULL({command.MLIDDT}) and {COMMAND.mliddt} > 0 then
DATE(CDBL(LEFT(CSTR({command.MLIDDT},0,""),4)),
     CDBL(MID (CSTR({command.MLIDDT},0,""),5,2)),
     CDBL(RIGHT(CSTR({command.MLIDDT},0,""),2)))
