Constants, yes, including quoted constants with trailing blanks. But
not variables with trailing blanks. In effect, near as I can tell,
when the CALL command is analyzed, it's done after variable
substitution.

The variable value becomes part of the CALL command string. For
subsequent purposes, the variable is then out of the picture. The
value effectively is converted into a constant, and the length of
that constant at that point doesn't include the trailing blanks from
the variable.
