Q57795: FORTRAN READ Statement Hangs in OS/2 If Called from BASIC
Article: Q57795 Product(s): See article Version(s): 6.00 6.00b 7.00 Operating System(s): OS/2 Keyword(s): ENDUSER | buglist6.00 buglist6.00b buglist7.00 SR# S900103-146 | mspl13_basic Last Modified: 17-JAN-1990 When running under MS OS/2, a Microsoft BASIC program LINKed with a FORTRAN routine that contains a READ statement will hang during execution. The same program compiled and linked under MS-DOS will run correctly. This problem occurs in Microsoft BASIC Compiler Versions 6.00 and 6.00b for OS/2 and in Microsoft BASIC Professional Development System (PDS) Version 7.00 for OS/2. Microsoft is researching this problem and will post new information here as it becomes available. The following two programs will hang when run. To demonstrate these programs from an .EXE program, compile and link as follows with the BASIC compiler and Microsoft FORTRAN Optimizing Compiler Version 5.00: BC /O /Lp BAS; FL /c /FPi /Lp FOR.FOR ; LINK /NOE /NOD BAS FOR,,,BCOM60.LIB LLIBFE.LIB; Please note that the above FORTRAN library LLIBFE.LIB may be called LLIBFEP.LIB, depending on how you installed FORTRAN. Code Example ------------ The following BASIC program is BAS.BAS, which calls a FORTRAN procedure: DECLARE SUB FPROG() DIM A%(500) COMMON SHARED /NMALLOC/ A%() PRINT "Calling FORTRAN" CALL FPROG END The following program is FOR.FOR, which prompts you for input and then should display the entered value: SUBROUTINE FPROG() INTEGER i WRITE (*,*) 'Please enter i' READ (*, *) i WRITE (*, *) 'This is i:', i END BAS.EXE produces the following output, and then hangs: Calling FORTRAN Please enter i
