GLOBALS

The GLOBALS statement declares modular variables that can be exported to other program modules. It can also import variables from other modules.

filename is a quoted string that specifies the pathname of a file that contains the GLOBALS . . . END GLOBALS statement (and optionally the DATABASE statement, but no executable statement). The filename can include a pathname. The .4GL file extension is required.

In general, a program variable is visible only in the same FUNCTION, MAIN, or REPORT program block in which it was declared. To make its scope of reference the entire source module, you must specify a modular declaration, by locating the DEFINE statement outside of any program block.

To extend the visibility of one or more modular variables beyond the source module in which they are declared, you must take the following steps:

Declare the variable in a GLOBALS . . . END GLOBALS declaration in a .4GL file that contains only GLOBALS, DEFINE, and DATABASE statements.

Specify that file in GLOBALS "filename" statements in each additional source module that includes statements referencing the variable.

These files must also be compiled and linked with the 4GL application.
