EXISTS ( String  VAR, Qualifier  PROC   ) Check if a global variable of a given name exists. Note that you cannot type EXISTS:VAR("w1.x") as w1.x is not a variable. Instead you need to split the operation into two parts and use EXISTS("w1") to check for the workspace and FIELD_PRESENT("w1","x") to check for the workspace field. Parameters: VAR  Object name to check PROC  Treat name as a PROCEDURE name rather than a variable name Returns: Boolean $TRUE or $FALSE See also: FIELD_PRESENT
