 Invoke SOLVE or INTEG in the usual manner. Invoke SOLVE or INTEG in the usual manner.
 This procedure utilizes indirect storage to make the RPN program more flexible. SOLVE and INTEG feed the each value of the floating variable as input to the user program, which immediately stores the value indirectly to its user-chosen register. Each variable in the function is then recalled for use in calculations, so the user program need not be structured to receive any particular variable from the stack. This procedure utilizes indirect storage to make the RPN program more flexible.
