You could use a parameter or a global variable to do that.

Global variables are "visible" through entire Forms session. You'd set it once and it remains the same until the session is over or you explicitely erase its value (or change it).

Let's assume that your login form has a text item called "login_block.user_name". When the WHEN-VALIDATE-ITEM trigger does its job (validates that user entered a correct value), you'd set global variable's value as

:global.user_name := :login_block.user_name;

Call another form using CALL_FORM, OPEN_FORM or NEW_FORM. There's no need to transfer global variable's value as it is already set and ready to be used in another form(s).

Delete its value using

erase('global.user_name');
