SQLBase IF statement

I am quite new to SQLBase and I've been struggling for a couple of days now, is it possible to write an IF statement in a standalone script? Something like:

IF EXISTS (SELECT * FROM SYSADM.SYSTABLES WHERE NAME = 'TMP') THEN
    DROP TABLE TMP
END

or

IF NOT EXISTS (SELECT * FROM SYSADM.SYSTABLES WHERE NAME = 'TMP') THEN
    CRETE TABLE TMP ...
END

Store a simple procedure , and run it from SQLTalk or TeamDeveloper . Optionally send in the Table name as a parameter and run it with 'Execute SYSADM.MyProc \TMP/ ' , or store the Proc with no parameters and hardcode the Table Name, and simply 'Execute SYSADM.MyProc'

ps Dont forget the SqlClearImmediate() !

store MyProc
PROCEDURE: table_proc static
PARAMETERS:
	String: psTableName
Local Variables
	Boolean: bExists
Actions
	On Procedure Startup
		If SqlExists('Select 1 from SYSADM.SYSTABLES where Name = :psTableName' , bExists )
			If bExists
				Call SqlImmediate('Drop table TMP')
			Else
				Call SqlImmediate('Create Table TMP(col1 int )'  )
			Call SqlClearImmediate()
