About Input Parameters and Prompts
INPUT variables may be specified at the beginning of the listing. A typical use of an INPUT variable is to supply a value for a dimension. This is a parameter later used in a relation or as input for model names used in assemblies.
Input Parameter Types
The INPUT statement must indicate the name and type of the variable. Variable names must always begin with a character.
The following variable types are supported:
Number—Enter a number for this variable type.
String—Enter a string of characters for this variable type. This enables you to enter parameters or model names, but not user attributes.
YES_NO—Enter either Y or N for this variable type.
 
* If no type is specified for the variable, the system default is Number.
