These single character commands will allow you to group appropriate code together without worrying about program flow.
x = UserUDF(y)
{
func UserUDF UUDFVar
ret UUDFVar+5
}
When the program is running it will execute the = (EQUAL) command but will skip all other commands after the = until the next command after the }. However, the commands within the braces are not invisible. They are still executed as part of the UDF. The only purpose for these controls is to keep related code together within your program.
