Hackers Guide to Visual FoxPro 7.0

_PLength, _PLineNo

These variables are part of the printer control system for streamed output produced with ? and ??. _PLENGTH determines the length of a page, and _PLINENO determines the current line number.

None of this has anything to do with reports generated in the Report Designer.

Usage

_PLENGTH = nPageSizeInLines nPageSizeInLines = _PLENGTH _PLINENO = nNextLineToUse nNextLineToUse = _PLINENO

_PLENGTH and _PLINENO interact with the ON PAGE command to determine when that command's event fires.

Setting _PLINENO doesn't change where the next line appears. It simply changes where the streaming output engine thinks it's printing.

Example

* See ON PAGE
