COMPUTE IS_A_SIC_VAR

        [SIC\]COMPUTE OutVar IS_A_SIC_VAR InVar

    Determines  whether  InVar (Character string) is the name of an existing
    SIC Variable or not.  OutVar must be a scalar Logical variable.

    The functionality is similar to the build-in SIC function EXIST, but EX-
    IST  would  complain  about invalid filenames as arguments.  Here, InVar
    can be any arbitraray string.

    This command is used in some scripts to determine silently  whether  its
    arguments  are File names, variable names or other expressions (see e.g.
    p_load.greg for an application.)
