Subj : How do I use a variable in a command

On the C64 I have an ML Routine that displays a directory.
The format for the command is SYS850,"$:*"
I need to insert a variable into the $ string. So that in a program I
can display filenames that start with a letter.

For example, I want to display all file names that start with I. so

10 A$="I":sys850,"$:"+A$+"*"

will not work.
Does anyone know a way to do this?

TIA
