Note: Functions with parameters

Parameters in SCS can be one of two types:

Function parameters extend the function defined by the function code. For example, the PP control function has a function parameter to explicitly define the positioning function performed. The form for a function parameter is a single EBCDIC character.
Value parameters specify a numeric value for the function. For example, the PP function also has a value parameter for it. If the move is relative to the current position, the value parameter specifies the number of columns or lines the presentation position is to be moved from its current position. If the move is absolute, the value parameter specifies the absolute column or line number to which the presentation position is to move. The form for a value parameter is a 1-byte binary number.
