2937.0. "restriction with TEXT_FILE SET TEXT_ATTRIBUTES" by SOS6::PROT () Tue Jun 29 1993 19:17

    I find a limitation with TEXT_FILE SET TEXT_ATTRIBUTES command, with
    ALL-In-1 V3.0.
    
    In WPSPLUS V4 you can define a character as Superscript and Bold for
    example. Internally, these 2 renditions are stored in 2 bytes in the
    text attribute part of the record: "Decimal 2" for the Bold and
    "Decimal 16" for the superscript.
    
    But with TEXT_FILE SET TEXT_ATTRIBUTES I can only address one of these
    two bytes, then set one rendition by position, then one rendition by 
    character.
    
    I can only set Q for superscript or B for bold but not both.
    
    Is it a known restriction?

	Louis, remember this is an unofficial support channel. since this appears to be a WPS-PLUS related question you could ask in their notes file. For an official answer you submit SPRs. Regards, Andrew.D.Wicks
2937.3	hmmm	SOS6::PROT		`Thu Jul 01 1993 18:45`	8
	Yes I know that it isn't an official support channel nevertheless someone (especially in eng) could know a special attribute or undocumented feature which could help me. Maybe my question wasn't right clear. Louis
2937.4	A restriction	IOSG::NEWLAND	Richard Newland, IOSG, REO2-G/L2	`Mon Jul 05 1993 23:25`	23
	I've looked at the TEXT_FILE code and this is a limitation. The SET TEXT_ATTRIBUTES sets each character attribute from the info-symbol value, and there is not an attribute letter for the combination of attributes you want (Bold and Superscript). It is probably not practicable to create more 'attribute letters' for all possible combinations of attributes. Therefore removing this limitation would require some way of calling SET TEXT_ATTRIBUTES multiple times to set multiple attributes. For example, add a /MORE qualifier which would add the specified attributes to the current attributes. Supporting all possible combinations of attributes with a RETURN TEXT_ATTRIBUTES is harder. One idea I have is to allow TEXT_ATTRIBUTE to accept an optional qualifer (e.g. /BOLD, /UNDERLINE, /SUPERSCRIPT) so that it returns only the attribute information requested. Only one qualifier would be allowed with each call. Any alternative ideas on how to extend SET and RETURN TEXT_ATTRIBUTES are most welcome. Richard
2937.5	ENHANCE TEXT_FILE functions!	SUOSWS::HAMANN		`Tue Jul 06 1993 12:03`	31
	Hi Richard, I had some similar problems using the TEXT_FILE functions. My problem was to convert an OfficeVision document to WPS+, and I could have done better if the TEXT_FILE functions had been less restrictive. So I would back some sort of enhancment. I would not suggest to change the current TEXT_FILE RETURN TEXT_ATTRIBUTES id returnsymbol -functions but to provide an additional enhanced function, something like TEXT_FILE RETURN ALL_TEXT_ATTRIBUTES id symbol1 symbol2 and bitencode the attributes in the symbols. To avoid control characters you might want to use only 6 bits/characters. The attribute 'special' should be expanded a bit more. Similary a TEXT_FILE SET ALL_TEXT_ATTRIBUTES id symbol1 symbol2 function could be provided. I hope some enhancement will be made available Klaus Hamann
2937.6	opinion.	PRSSOS::PROT		`Thu Jul 15 1993 13:11`	6
	I agree with the last suggestion , a bit mask for all the current attributes could be powerfull to modify and set. But the .4 suggestion /MORE could also be easy to use. Louis
