For transcript or data files on your PC, enclose file names within angle brackets, < >. All characters within the brackets are taken literally, but underscore characters are not allowed. File names may be stored in variables. For example:
CAPTURE ON <transcript> \* a literal file name
_var = <new script> \* assign a file name
\* to a variable
EXEC _var \* execute a script
\* whose name is in _var
CAPTURE OFF <>
