Re: Parameter from one form to another form

This must be asked and answered thousand times but here it is again: - in your calling form define a global variable like this :GLOBAL.your_variable := 10;

• in the called form define the same global variable like this (for example in key-start-up trigger or somewhere else where the global variable is used first time)

DEFAULT_VALUE(NULL,'GLOBAL.your_variable'); - this means that :GLOBAL.your_variable value is NULL by default if it wasn't given any value in the calling form (or the form is called from somewhere else)
- and when you need the global variable in the called form use it like any other variable (only you don't have to declare it again) for example like this
Message(':GLOBAL.your_variable value = ' || :GLOBAL.your_variable);

And it would be good programming if you would erase the GLOBAL.your_variable after you don't need it anymore. It is case sensitive that shoul it be on the form that calls another form or should it be on the called form. Anyway on that form's key-exit trigger that handles the GLOBAL.your_variable last time. The command is like this
ERASE('GLOBAL.your_variable');

By the way, look very carafully where I used : before GLOBAL word and where not. Received on Sun Aug 15 1999 - 02:20:45 CDT
