Hi Richard,


I wasn’t sure whether this message, below, was to let us know that you wanted one of us to install the latest SWCHAR into the ITS github repo, or whether you were just letting us know that a new one was developed.


I did just make a tape from TT with your latest SWCHAR, and I could add to the ITS repo, but I wanted to check with you first.  


Should I?  I see


swchar urs011




swchar urs016


Do you want me to put in a PR to merge SWCHAR URS016 into the DB build of ITS?

Hi Lars and Eric and everybody,


I have just finished the Muddle software generator package for MIGS. 

It's called "RRS;SWCHAR >" and has three main entry points. 

They are SWTEXT, CHARGE, and MCHARG and uses the SSV character set. 


SWTEXT displays a line of text on the screen. It's only required argument is a text string everything else is optional. 

The optional arguments are the X and Y position on the screen and the Space between  characters.


CHARGE Displays one character at position X, Y on the screen. It has an optional argument the scale factor is set to 1, 

The normal size of the SSV character set. 


MCHARG is the same as CHARGE, but is only used inside an MCELL() or PICT()



SWTEXT is a little slow, the compiler would really help. It's main purpose is to ride short sequence of characters that you want to position anywhere in 3 space,

or rotate to any direction. You don't want to use SWTEXT for displaying a whole page of text.


Below is a example of the use of SWTEX.
