/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// NTH I Index of symbol to be fetched.
/// TABSYM,
/// TABPTR,
/// TABVAL I Components of the symbol table.
/// NAME O Name of the NTH symbol in the symbol table.
/// FOUND O .TRUE. if the NTH symbol is in the symbol table.

///
/// # Detailed Input
///
/// ```text
/// NTH is the index of the symbol to be fetched. If the NTH
/// symbol does not exist, FOUND is .FALSE.
///
/// TABSYM,
/// TABPTR,
/// TABVAL are the components of a character symbol table.
/// The NTH symbol may or may not be in the symbol

///
/// ```text
/// 1) If there is an issue while reading the components of a

/// The contents of the symbol table are:

/// BOHR --> HYDROGEN ATOM
/// EINSTEIN --> SPECIAL RELATIVITY
/// PHOTOELECTRIC EFFECT
/// BROWNIAN MOTION
/// FERMI --> NUCLEAR FISSION
///
/// The calls,
///
/// CALL SYFETC ( 2, TABSYM, TABPTR, TABVAL, NAME, FOUND )
/// CALL SYFETC ( 3, TABSYM, TABPTR, TABVAL, NAME, FOUND )
/// CALL SYFETC ( -1, TABSYM, TABPTR, TABVAL, NAME, FOUND )
