Low Level Parser Storage

These procedures store parameters (attributes) to the parser, symbols,
symbol variables, symbol derivatives, and symbol fitting parameters, in
the parser common, and the parser symbol table. 
.sp
These should be the ONLY procedures that access the parser common and
symbol table directly, by using the macro definitions in prtable.h.
All other procedures should try to use these procedures as the entry
point to access any common or symbol table parameter.

.nf
Entry points:

	int = pr_putsym (name)			Put symbol into table

	pr_psym (number, type, value)		Put symbol pointer by number,
						and type

	pr_put[ip] (param, value)		Put general parameter

	pr_inc[i] (param, value)		Increment general parameter
	pr_dec[i] (param, value)		Decrement general parameter

	pr_psym[cirp] (offset, param, value)	Put symbol parameter

	pr_pvar[i]  (offset, nv, param, value)	Put variable parameter
	pr_ppar[ir] (offset, np, param, value)	Put fitting parameter parameter
	pr_pder[cp] (offset, nd, param, value)	Put derivative parameter
