MacSpice specifications

Enhancements:

• Errors and warning messages generated by scripts now attempt to identify the location of the line that caused them.
• Blocks with missing end statements now generate warning messages.
• Vectors with one element are no longer automatically converted to scalars.
• Command line interpreter now evaluates variables of the form ${foo}
• Improve 'load' command so that invalid rawfiles are less likely to cause hangs/crashes.

Bugs fixed:

• Fixed missing breakpoints for pulse sources. (Build 245)
• Modify behaviour of 'set' command so it creates a string variable in cases like 'set foo = "123 abc"'
• Fixed a potential crash when expressions like {$foo} are evaluated if more than 1GB of memory is reserved.
• Fix crash when 'plot' is followed by no arguments and two carriage returns.
• Fix crash when an 'else' block is empty.
• Fix crash in gr_pmsg() during iplot runs.
