Q58043: PLAY "Illegal Function Call" for "B+","C-","E+", and "F-"
Article: Q58043 Product(s): See article Version(s): 1.00 1.01 1.02 2.00 2.01 3.00 4.00 4.00b 4.50 Operating System(s): MS-DOS Keyword(s): ENDUSER | buglist4.00 buglist4.00b buglist4.50 B_BasicCom B_GWBasicI | mspl13_basic Last Modified: 20-SEP-1990 The PLAY statement causes an "Illegal Function Call" error when given any of these notes: "B+", "C-", "E+", or "F-". These are valid notes (since they are the equivalent of natural notes) and should not cause the error. Microsoft has confirmed this to be a problem in QuickBASIC versions 1.00, 1.01, 1.02, 2.00, 2.01, 3.00, 4.00, 4.00b, and 4.50; in Microsoft BASIC Compiler versions 6.00 and 6.00b (buglist6.00, buglist6.00b); in Microsoft BASIC Professional Development System (PDS) versions 7.00 and 7.10 for MS-DOS (buglist7.00, buglist7.10); and in Microsoft GW-BASIC versions 3.23, 3.22, and 3.20 (buglist3.20, buglist3.22, buglist3.23). We are researching this problem and will post new information here as it becomes available. To work around this problem, check for those notes and use their natural equivalents (listed below). The following table lists the errant notes and their equivalents for the workaround: Errant Note Equivalent ----------- ---------- B+ C C- B E+ F F- E By using the workaround listed above, the following statement would changed as follows: PLAY "B+C-E+F-" 'changed to PLAY "CBFE" Additional reference words: buglist1.00 buglist1.01 buglist1.02 buglist2.00 buglist2.01 buglist3.00 SR# S900117-43
