; NAME:
; BETA
; PURPOSE:
; The introduction of the BETA function as a built in system routine
; in IDL 4.0 caused inconvenience to customers with existing code
; in which BETA had been used as a variable, because IDL system
; routines have precedence over variable names. To minimize this
; problem, RSI has renamed BETA back to NR_BETA (its old name).
;
; This wrapper serves to make NR_BETA available under the name
; BETA as documented in the IDL Reference Manual. However, since
; IDL library routines have lower precedence than variables, programs
; that use BETA as a variable name will work as before.
;
; See the documentation for BETA in the IDL Reference manual for details
; on arguments, keywords, and results.
;
;
; MODIFICATION HISTORY:
; 3 July 1995, AB, RSI.
