Is there an easier way to convert a string representation of dates in format 'YYYYMMDD' and 'YYYYMMDDHHMM' than using the trim functions?

What are you trying to do?  DO you have date fields you are converting to strings?

The database that I am using stores dates as string in the form: YYYYMMDD because it is much more efficient when searching.

I am using an ODBC connection to the back end and can only get the date info in this form which I must translate to a more conventional date format, for example, using VB's midstr() function, to cut up the string and reformat. I would like to bye pass this extra parsing step, if possible

Not really but you can do the entire conversion in a CR formula

Something like
Change D to your DATE field

cdate (left(D,4) & "/" & mid(D,4,2) & "/" & right(D,2))

For the DATETIME

datetime (tonumber(left(DT,4)),tonumber(mid(DT,4,2)), tonumber(mid(DT,6,2)),tonumber(mid(DT,8,2)), tonumber(right(DT,2)),0)

DATETIME requires (YYYY,MM,DD,HH,MM,SS)  since you don't have the seconds I added the 0.  If you have seconds use

datetime (tonumber(left(DT,4)), tonumber(mid(DT,4,2)),  tonumber(mid(DT,6,2)), tonumber(mid(DT,8,2)), tonumber(mid(DT,10,2)), tonumber(right(DT,2)))

good luck
