PRINT (or ?) outputs values. A value can be a variable, a constant or an expression of arbitrary type. The given values have to be separated by the '; ' or ', ' . In addition these separators have the following effects on formatting:

;	The values are printed without further separators.
,	A tabulator is inserted between the values.

If one of the two separators stands at the end of the parameter list, then no line feed takes place.
The format how floating numbers are display, can be changed with SETFFORMAT.
