Subject:      Re: Removing Trailing Blanks from a Macro variable and Index

It's important to distinguish between a macrovariable's name and its value.

The first argument to SYMPUT provides the name and the second provides the
value.

Try using the TRIM function on the value, which comes from the data step
variable _SOURCE_.

   call symput (trim('IndepVar'||ii),trim(_SOURCE_));
