Below is a summary of the content of an input deck for a One-Step analysis. Each card is defined in its rigid format form and is shown as a number of fields with a length of 10.

In the following listings:

•The Type is the variable type and is either F, for floating point, I for an integer, or C for a character. The default gives the value set if the field is left blank or the card is not defined.
•Any variables used for property ID as keywords should be positive and defined in the corresponding property card, which will share the same color.
•Any card in italic is optional.

 

The @HyperForm line is the first line of the file, in the parameter section.

The following cards appear in the bulk data section, between "Begin Bulk" and "ENDDATA".
