RE: CWCCVTDT continued....

The length on the prototype is not a field declaration. It is the limit of the
size of the value you can pass to the program/procedure. So 64 or 65535 makes no
difference in this prototype in this context.

I'm curious Bob. I just checked IBM's website and it still looks like
this for the input variable to the API:

Input Variable Format
This table shows the format used for the input variable parameter.

Input Format Input Variable 
*CURRENT Parameter is ignored. 
*DTS System time-stamp. The first 8 characters are used. 
*YYMD, *MDYY, *DMYY, *LONGJUL The first 17 characters are used. See
17-Byte Character Date and Time Value Structure. 
All other character formats The first 16 characters are used. See
16-Byte Character Date and Time Value Structure. 

 
Why define 64 with a variable size? Wouldn't 17 be enough?

Thanks
