Q28591: BC.EXE "Argument-Count Mismatch" Compiling Underscore in CALL
Article: Q28591 Product(s): See article Version(s): 4.00 4.00b Operating System(s): MS-DOS Keyword(s): ENDUSER | B_BasicCom buglist4.00 buglist4.00b fixlist4.50 | mspl13_basic Last Modified: 31-JAN-1990 Inserting a line-continuation character (underscore) between the subprogram name and the argument list in a CALL statement produces an "Argument-count mismatch" message when compiled with Microsoft BASIC Compiler. If the subprogram is not DECLAREd, a "Syntax error" message results. Microsoft has confirmed this to be a problem in QuickBASIC Version 4.00 and 4.00b and in Microsoft BASIC Compiler Versions 6.00 and 6.00b for MS-DOS and OS/2 (buglist6.00 buglist6.00b). This problem was corrected in QuickBASIC Version 4.50 and in Microsoft BASIC Professional Development System (PDS) Version 7.00 for MS-DOS and MS OS/2 (fixlist7.00). If an underscore is inserted at any other point in the CALL statement (between the CALL and the subprogram name or in the argument list), it is properly recognized as a line-continuation character. This problem does not occur in the editor because the editor removes continuation characters. Note: DECLARE statements are not supported in earlier versions of QuickBASIC. If the DECLARE statement is removed and STATIC is added to the SUB statement, QuickBASIC Versions 2.00 and 3.00 handle the underscore properly. To work around the problem, move the continuation character to some other point in the CALL statement. The following example works correctly: CALL_ a(b) The following code example shows the problem: DECLARE SUB a (b) CALL a_ (b) SUB a (x) END SUB
