Hi again! I need to be able to specify not only 16 bit sizes but also 8 bit and 4 bit sizes as well. Is there anyone out there that could give me a hint of HOW to implement the functionality in GPC and some kind of estimation of how long TIME it would take?

Date: Tue, 31 Jul 2001 16:34:50 +0200 From: Sven Jauring <sven.jauring@hiq.se> To: gpc@gnu.de Hi, I'm working in a project, where I need to compile old pascal code using GPC (beta 20010201). The code is scattered with variable types, that depends on bit correlations in unions. E.g: ******************************** type INT0_255 = packed 0..255; BITS = (BIT0,BIT1,BIT2,BIT3, BIT4,BIT5,BIT6,BIT7, BIT8,BIT9,BIT10,BIT11, BIT12,BIT13,BIT14,BIT15); var VARIABLE1 : record case int16 of 0: (WORD: INTEGER); 1: (MSB: INT0_255; LSB: INT0_255); 2: (BT : set of BITS); end; ********************************* In order for this declaration to function properly, I seem to need the possibility to specify 'BT' to be just 16 bits, and not 32 bits, which seems to be default. I tried to find out from the manual if this is possible. I found the following passages: "The Extended Pascal features still missing from GPC are ..., set types with variable bounds, ..." and "Planned features: Other types... *sparse sets; sets of arbitrary types ?? ???" For me, this is pretty deep water, so I won't take offence if you tell me to RTFM, but never the less... My question is this: Can it be done in the latest release (20010623) or should I wait for someone to implement this feature? Best Regards Sven Jauring
