system time.
2. I meant to assign an empty string to a variable in a data step nested
within macro. Though I could type out quoted empty string, it doesn't look
very professional.

Usually I use the value of a global macro var as the prefix of temporary
datasets and change it (++1) after each macro execution.
2. You mean string containing only blanks? SAS does have repeat function to
do that.
current
