## Exp(x) 

an arithmetic function that computes the real value of e (the base of naturalloga­ rithms) raised to the real or integer parameter x. 

## Get (f) 

a file-handling procedure that causes the position in the sequence f to be ad­ vanced to the next component, if any, and f" to take on its value; if no next component exists eo f ( f) becomes true and f" becomes totally undefmed. Ge t (f) is an error if f is undefined or eof (f) is true. If f is omitted, program parameter Input is assumed. 

## Ln(x) 

an arithmetic function that computes the real natural logarithm (to the base e) of the real or integer parameter x, where x > O. Ln (x) is an error if x<=o. 

## New(p) 

a dynamic-allocation procedure that allocates a new identified (dynamic) vari­ able pi having the domain type of p and creates a new identifying pointer value hav­ ing the type possessed by p and assigns it to p. If p" is a variant record, New (p) allocates enough space to accommodate all variants. 

## New (p, el, ... , en) 

a dynamic-allocation procedure that allocates a new identified (dynamic) vari­ able pi having the variant record type of p with tagfield values e I, . . . , en for n nested variant parts, and creates a new identifying pointer value having the type pos­ sessed by p and assigns it to p. 

## Odd(i) 

a Boolean function that returns t rue if the integer parameter i is not evenly divisible by 2; returns fa 1 s e otherwise. 

## Ord(x) 

a transfer function that returns the ordinal number (an integer) of the ordinal pa­ rameter x in the set of values defined by the type of x. 

## Paek(u,i,p) 

a data-transfer procedure that packs the contents of the non-packed array u start­ ing at component i into the packed array p. 

## Page (f) 

a file-handling procedure that causes an implementation-defined effect on the textfile parameter f such that the next line subsequently written to f will appear at the top of a new page when f is printed. If f is not empty, and the last component of its sequence is not an end-of-line marker, then Page (f) performs an implicit Wr i­ tel n (f). If the parameter list is omit
