Debugging PDF Output Problems

Define a PDF form and set "Print Grid" to "Y", then, define an environment variable named APPX_GRID_STYLE to control the grid settings. The default value for APPX_GRID_STYLE is 15 (decimal). To change the grid style, just add up any of the following numbers:

 1 - draw horizontal grid lines at grid boundaries
 2 - draw vertical grid lines at grid boundaries
 4 - label horizontal grid lines
 8 - label vertical grid lines
16 - subdivide grid height into 1/10 intervals
32 - subdivide grid width into 1/10 intervals
64 - draw outlines around all widgets

So, the default APPX_GRID_STYLE gives you labeled horizontal and vertical grid lines (1 + 2 + 4 + 8 ) on every page.

APPX_GRID_STYLE=64 is very useful
