    A Fortran IV program to draw enhanced graphic characters



    A FORTRAN subroutine SYMBEL is described which enables the drawing of the enhanced graphic characters of Dr. A. V. Hershey on any digital plotting device. Output is by linkage to an external subroutine PLOT. The program operates on any computer with integer binary arithmetic and at least a 30 bit word length.
