The following table explains each variable and array.

This array or variable:	Is:
MD array	Main storage array for Adams Solver analysis.
OPRM array	The memory section for interactive modification of function expressions, user-written subroutines, arrays, splines, and more. This array is specified as a subset of the MD Array, and does not increase the size of the MD Array.
CD array	Used to store column titles and spline types.
LD array	Used to store character strings, request comments, function expressions, and more.
LCEXPR	The maximum number of lines in any function expression.
FPSIZE	The maximum number of real constants in any single expression. Real constants are decimal place numbers that cannot be represented as integers; 2.1 for example but not 2.0.
NINSIZ	The maximum number of RPN (Reverse Polish Notation) instructions in all function expressions.
MXSTAK	The maximum size of the RPN stack.
