Variables Not Allowed in CASE Statement of SELECT CASE Block (43264)

SUMMARY

The SELECT CASE block does not allow variables in the CASE statements. As an alternative, using multiple IF statements is recommended.

Code Example

The following code example gives a "Syntax Error" on the CASE x line:

x=1
y=1
SELECT CASE y
CASE 0
  PRINT "Zero"
CASE x                ' This line causes error
  PRINT "XXX"
CASE ELSE
END SELECT
				

This is an example of the workaround using multiple IF statements:

x=1
y=1
IF y=0 THEN
  PRINT "Zero"
ELSEIF y=x THEN
  PRINT "XXX"
ELSE
END IF
