Conditional Statements

The scripting language has one type of conditional statement - the IF..THEN..ELSE statement. The syntax of this statement is as follows:

IF <expression> THEN
     <statement block>
[ELSE
        <statement block>]
ENDIF

You can use the conditional statement without ENDIF, if the whole statement fits into one line:

IF <expression> THEN <statement block>

The result of the expression must be of type Integer.

• If the expression is TRUE (nonzero value), the statement following THEN is executed.
• If the expression is FALSE (zero value) and the ELSE part is present, the statement following ELSE is executed.
• If the ELSE part is not present, program execution continues at ENDIF.

Note: Instead of ENDIF you can use End If.

Another form of the conditional statement deals with nested conditional statements. Instead of coding nested conditional statements as shown in the first code sample that follows, you can code them as shown in the second sample.

DIM os As String
.
.
.
If os = "AIX" Then
	aixRun()
Else
	if os = "HPUX" Then
		rc = hpRun()
	Else
		if os = "SOLARIS(sparc)" Then
				solarisRun()
		else
				print("unknown os type: " + os)
		End If
	End If
End If 
.
.
.

Second sample:

DIM os As String
.
.
.
If os = "AIX" Then
	aixRun()
Elseif os = "HPUX" Then
	hpRun()
Elseif os = "SOLARIS(sparc)" Then
	solarisRun()
else
	print("unknown os type: " + os)
End If 
.
.
.

Example:

DIM ProgName as String
DIM ProgPath as String
ProgPath="C:\AVIRUS"
IF InStr(ossystem,"DOS") THEN 
ProgName=ProgPath + "FINDVIRU.EXE"
ELSE
ProgName=ProgPath + "WFINDVIR.EXE"
ENDIF
end:
