Q27385: LINE INPUT to Fixed-Length String Crashes QB.EXE Interpreter
Article: Q27385 Product(s): See article Version(s): 4.00 Operating System(s): MS-DOS Keyword(s): ENDUSER | ptm37 fixlistbc6.00 buglist4.00 fixlist4.00b fixlist4.50 | mspl13_basic Last Modified: 7-NOV-1988 Using a fixed-length string to accept input in a LINE INPUT statement can hang the QB.EXE Interpreter. Microsoft has confirmed this to be a problem in Version 4.00. This problem was corrected in QuickBASIC Versions 4.00b and 4.50, and in the Microsoft BASIC Compiler Version 6.00 for MS-DOS and OS/2. The following is an example program showing the problem: DIM C AS STRING * 10 LINE INPUT C PRINT C Run the program and type 1 in response to the LINE INPUT. This will hang QB.EXE. The workaround for this problem is to LINE INPUT into a variable-length string and then assign to a fixed-length string.
