The following libraries defined in PIM are provided:
|InOut||general-purpose IO operations|
|LongInOut||LONGREAL numbers IO operations|
|RealInOut||REAL numbers IO operations|
|Terminal||computer's terminal IO operations|
The library LongInOut (similar to RealInOut) is not described in PIM. All PIM libraries are implemented on a basis of the ISO library. Since PIM Storage library is not compatible with the corresponding ISO library, it is omitted.
