 Compile your subs/functions to objs. Then...


 This subject is covered quite well in the manual, for more details look

 As far  as "standards" goes the parameters you pass to the
 subs/functions in your library need not have the exact same name(s) but
 they must be the same type(s). For example, let's say you have a sub
 called "SearchReplace" in your qlb. Even if it's in a qlb/lib you still
 need to declare it at the head of your main module right? Like so....

 DECLARE SUB SearchReplace (OldString$, NewString$, errcode%)
                            ^^^^^^^^^^  ^^^^^^^^^^  ^^^^^^^^
                                |           |           |
 when you call it you don't have to use these parameter names _but_ you
 must use the same parameter types and in the same order. That is, when
 you call this sub the parameter order and type MUST be 'string, string,
 integer' right? These would be valid calls to your sub...

           CALL SearchReplace (FoundStr$, ReplaceStr$, RetCode%)


           CALL SearchReplace ("many", "mucho", returnerr%)

 The following calls would NOT be valid...

           CALL SearchReplace (RetCode%, FoundStr$, ReplaceStr$)


           CALL SearchReplace (OldString$, NewString$)


           CALL SearchReplace (OldString$, NewString$, errcode!)
                 [wrong numeric variable type]----------------+

 In the above 3 examples the parameters are not listed in the correct
 order or the parameter count is different or they are not the same
 type. Does that help you out any?
