The INDIVIDUALS indicator card is used to announce the definition of function and derivative values for the types of nontrivial group functions required. The syntax for data cards following the indicator card is given in Figure 5.2.1.
Figure 5.3: Possible data cards for INDIVIDUALS
The one- or two-character string in field 1 specifies the type of data contained on the card. Possible values for the first character of the string are:
is made; any variable mentioned in the arithmetic expression must either be reserved (see Section 5.2), or have been defined in the TEMPORARIES section. If, in this latter case, the variable is integer or real, it must have been allocated a value itself either on a previous GLOBALS data card or on a previous A card for the current element type in the INDIVIDUALS section.
will be made if and only if the logical auxiliary parameter, l-name, specified in field 2 has the value .TRUE.; the logical parameter must have been previously defined in the TEMPORARIES section and allocated a value in the GLOBALS or INDIVIDUALS section. The arithmetic expression must obey the rules set out in the A section above.
will be made if and only if the logical auxiliary parameter, l-name, specified in field 2 has the value .FALSE.; the logical parameter must have been previously defined in the TEMPORARIES section and allocated a value in the GLOBALS or INDIVIDUALS section. The arithmetic expression must obey the rules set out in the A section above.
is made; any variable mentioned in the expression must obey the rules set out in the A section above.

is made; any variable mentioned in the arithmetic expression must obey the rules set out in the A section above.
The data started on an A, I, E, F, G and H card may be continued on a card whose first field contains an A+, I+, E+, F+, G+ or H+ respectively. Such cards contain an arithmetic expression in field 7 and no further data; the arithmetic expression must obey the rules set out in the A section above. At most nineteen continuations of a single assignment are allowed.
The data for a single group type must occur on consecutive cards and in the order given in Figure 5.3. A new group type is deemed to have started whenever a T card is encountered. The F card is compulsory for all group types.
