Global variables can be used throughout the whole forms session; therefore, yes - in "form2" you can use a global variable which was declared in "form1".

Look at the sample code in the 'clear_block' section of the reference manual. Remember that before testing a global you should do a 'default_value' command to make sure that the global is set to something. An unused global does NOT have a value of 'null'.
