No function .... just straight forward programming. You can create a function if you want.
month = (/"jan","feb","mar","apr","may","jun" \
,"jul","aug","sep","oct","nov","dec"/)
yyyymmdd = 20090402
yyyy = yyyymmdd/10000
mmdd = yyyymmdd-(yyyy*10000)
mm = mmdd/100
dd = mmdd-(mm*100)
print("yyyy="+yyyy+": mm="+mm+": dd="+dd)
DATE = sprinti("%0.2i", mm) + month(mm-1) + yyyy
print(DATE)

I think you want cd_string, not cd_convert:

It looks like cd_convert is used to convert various linear time units, ex, "days from..." to "months from...", etc.

Hi
in my code, I have extracted the dats which looks like 20090402 (2nd April2009).I have to convert it to the format 02apr2009.
I am using cd_convert to write the date and time in the required format.
Following is the lines from the code. I have added units to this variable YYMMDD
YYMMDD = stringtointeger(Split_name(1)) ; string variable
print(YYMMDD)
YYMMDD at units = "days since 0000-01-01 00:00:0.0"
; printVarSummary(YYMMDD)
stime = cd_convert(YYMMDD,"%c%y")
; print(stime)
I get error like this
CDMS error: Error on relative units conversion: invalid units = %c%y
kindly suggest
Geeta.
