-> Could someone PLEASE explain exactly how seperate modules work?  I'm

-> right size for the compiler, but it isn't working..  Can I call
-> subroutines from the 1st module from within a sub from the 2nd?  And
-> do I have variables that will work in both modules and in both module
-> subroutines?  I've found that DIM SHARED doesn't work across differen
-> modules..  Can somebody help me??


You need to use the COMMON SHARE statement.
Something like:

COMMON SHARED Array()
DIM Array(1 TO 100) AS SINGLE

The order of the COMMON SHARED statements is very important.  They
must appear in the same order in each module.  The best way to do that
is to create a separate INCLUDE file that contains your COMMON SHARED
statements.  You then use a line at the top of each module such
as:

'$INCLUDE: 'COMMON.BI'

The name COMMON.BI is just a file name you chose.  The DIM statements
appear just below the include statements only in your 1st main module.
You can call a SUB from anywhere in any module.
