1.5 Input management

FORTRAN 3D supplies input primitives independent from terminals, such as:

• Integer number
• Real number
• Character string
• Position
• Curve
• Identification

The management mode of the input methods is rather restrictive. An input request of one of the above devices results in a queue and can only be performed on one device at a time.

Lastly, in the library corresponding to FORTRAN 3D, the programmer disposes of a positioning input function via the successive entry of points on two orthogonal views.
