Hi,

Just trying to set a "line u:s41p" symbol on latest Therion and getting strange metapost errors:

! Missing `=' has been inserted.

<to be read again>

                   51

l.6846 let l_u_s51

                  p = l_u;

You should have said `let symbol = something'.

But don't worry; I'll pretend that an equals sign

was present. The next token I read will be `something'.

! Missing symbolic token inserted.

<inserted text>

                 INACCESSIBLE

l.6846 let l_u_s51

                  p = l_u;

Sorry: You can't redefine a number, string, or expr.

I've inserted an inaccessible symbol so that your

definition will be completed without mixing me up too badly.

! Extra tokens will be flushed.

                   p

l.6846 let l_u_s51p

                    = l_u;

I've just read as much of that statement as I could fathom,

so a semicolon should have been next. It's very puzzling...

but I'll try to get myself back together, by ignoring

everything up to the next `;'. Please insert a semicolon

now in front of anything that you don't want me to delete.

(See Chapter 27 of The METAFONTbook for an example.)

! Missing `=' has been inserted.

                   51

l.6847 def l_u_s51

                  p_legend = l_u_s51p(((-.3,0.5) .. (.3,.3) .. (.7,.7) .. (1...

The next thing in this `def' should have been `=',

because I've already looked at the definition heading.

But don't worry; I'll pretend that an equals sign

was present. Everything from here to `enddef'

will be the replacement text of this macro.

I believe that subtypes aren´t supporting all chars allowed by <keyword>  as defined in THBook page 13 (Data types).

Is it a bug or am I misreading something?

Regards,

Rodrigo
