2850.0. "request as local entity" by MICROW::LANG () Fri Apr 24 1992 13:13

    I have an MSL question.  We have a local entity, which we wanted
    to call REQUEST. That has meaning in the MSL.  Can that be used?
    When I try to use REQUEST, I get the error:
    
    MCCMSL-I-MSLLOCATION, Line: 56, File: mcc_tps_am_entity_request.ms,
    %MCCMSL-E-PARSER, syntax error: The value "REQUEST" is not expected
    
    Does this mean we can't use request?
    
    			thanks,
    					Bonnie

2850.1	request is reserved	TOOK::MATTHEWS	`Fri Apr 24 1992 19:23`	17
	I believe their are a number of keywords for MSL that can't be used for entity identifiers. Request, exception, directive, etc. The MSL translator is based upon lexical tools that look for keywords. We use SCAN in VMS and awk I believe for Ultrix. Since the lexical analyzer is unaware of the position context within the syntax, then it must reserve certain keywords for purely syntactic use. We could solve this restriction by creating an elegant parser but that is not a practical solution. So it is dangerous to use any of the syntactic keywords of MSL for anything else. If it works, it is purely accidental. I might suggest that you look for another word that has a similar meaning. wally
2850.2	Corrections: MSL keywords:	TOOK::L_GROSSMAN	`Mon Apr 27 1992 11:50`	7
	The msl keywords are only recognized in all uppercase, so if you can use "Request" or any other cobination as long at least one character is in lower case, it should work. Correction: The VMS and ULTRIX V1.2 DECmcc MSL translator is written with the ULTRIX tools Lexx and Yacc.
