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