The sample program below makes a call to the MS OS/2 functions
DosSetVerify and DosQVerify. This program can be compiled in Microsoft
BASIC Compiler Versions 6.00 and 6.00b for MS OS/2 and in Microsoft
BASIC Professional Development System (PDS) Version 7.00 for MS OS/2.

The program is as follows:

DEFINT A-Z

'The declarations can be found in BSEDOSFL.BI

DECLARE FUNCTION DosSetVerify%(_
                 BYVAL P1 AS INTEGER)

DECLARE FUNCTION DosQVerify%(_
                 SEG P1 AS INTEGER)

x=DosQVerify(opt%)

IF (x) THEN
  Print "An error occurred.  The number is : ";x
ELSE
  SELECT CASE opt%
     CASE 0
        Print "Verify is off"
     CASE 1
        PRINT "Verify is on"
     CASE ELSE
        PRINT "An unexpected error occurred."
  END SELECT
END IF

Print  "(0) to deactivate verify "
input  "(1) to activate for this Application : ";opt%

x=DosSetVerify(opt%)

IF (x) THEN
  Print "An error occurred.  The number is : ";x
ELSE
  SELECT CASE opt%
     CASE 0
        Print "Verify is set off"
     CASE 1
        PRINT "Verify is set on"
     CASE ELSE
        PRINT "An unexpected error occurred."
  END SELECT
END IF
INPUT "Enter Any Key to Verify the Status of VERIFY";a$

x=DosQVerify(opt%)

IF (x) THEN
  Print "An error occurred.  The number is : ";x
ELSE
  SELECT CASE opt%
     CASE 0
        Print "Verify is off"
     CASE 1
        PRINT "Verify is on"
     CASE ELSE
        PRINT "An unexpected error occurred."
  END SELECT
END IF
