SUMMARY

The QuickBasic TYPE...END TYPE statement must be physically at the top of the program. If it isn't, the program may not compile correctly. This information applies to QuickBasic Versions 4.00, 4.00b, and 4.50, Microsoft Basic Compiler Versions 6.00 and 6.00b for MS-DOS and MS OS/2, and Microsoft Basic PDS Version 7.00 for MS-DOS and MS OS/2.

The code example shown below does not compile correctly. In the QB.EXE editor, an error "Identifier cannot include a period" is reported on Line 2. In BC.EXE, two errors are reported, as follows:

Variable name not unique

Type Mismatch

To correct the program, move the TYPE ... END TYPE block and the DIM statement before the use of the variable. It is best to place these types of statements at the beginning of the program.

The following is sample code:

GOSUB initvar
  PRINT x.str
END

initvar:
        TYPE user
            str AS STRING * 10
        END TYPE
        DIM x AS user
        x.str = "hello"
RETURN
