The numerical equivalents for use in conjunction with the read symbol and 'print symbol' routines are given in the table overleaf. The table gives the numerical equivalents of the basic symbols i.e. symbols comprising of a single (upper or lower case) character. Up to three basic symbols may be superimposed (by means of the backspace facility) to form a compound symbol. For example:-
≠ is formed from = _ /
The numerical equivalent of a compound symbol is
a*2↑14 + b*2↑7 + c
where a,b,c are the numerical equivalents of the individual symbols, ordered so that a>b>c. Thus the numerical equivalent is independent of the order of punching the individual characters.
If only two symbols are used, the formula is
b*2↑7 + c, b > c
Thus ≠ is equivalent to 86*2↑14 + 28*2↑7 + 15 and ≥ is equivalent to 86*2↑7 + 27
