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".
