 PRINT FIELDS displays data anywhere on the screen except the status line. One field or several fields can be displayed with the PRINT FIELDS statement. PRINT FIELDS, INPUT FIELDS, RINPUT FIELDS, INPUT SELECT and RINPUT SELECT are all used for full screen processing. See the [[:Category:Field Specifications]] section for information and examples common to all of these statements.

	:1.) MAT grouping is now allowed in all [[full screen processing statements]]. This feature allows you to indicate that input or output should alternate between all MAT variables that are specified within parentheses in the I/O list. In the following code fragment, the A$ variable identifies the positions on the screen from which input values should be drawn. Business Rules! will assign the first input value to the first element of B$. However, because the B$ and C matrices are specified within parentheses, it will then assign the second input value to the first element of C. The third value will go to B$, the fourth to C, and so on until both matrices are fully assigned. The last input value will go to X$.		:1.)

	MAT grouping is a lot easier to code, executes faster, and most importantly, handles much larger arrays than are possible without using MAT grouping, as the resulting compiled line takes up less space in memory. The number of matrices that can be grouped together is 62, which in practical terms is no limit. All matrices in a group must have the same number of elements per matrix, or an error [[0106]] will result. Only MAT variables may be used in such groupings.
