Here's a little item that may be of interest, which is not documented in the (error) messages section of the manuals. Try this: STYPE \<< TYPE 263 + DOERR \>> In case you see an object, and you don't recognize what it is, you can run this program on the object, and it will tell you what it is. eg. if you find this on the stack after CHIP: <0h> STYPE will tell you that it is a System Binary from this you can deduce that an object of type 20 = System Binary (called shorts by some) type 21 = Long Real type 22 = Long Complex type 23 = Linked Array type 24 = Character type 25 = Code type 26 = Library Data type 27 = External of these object types, has anyone actually seen types 21,22,23,24 or 26 on the stack? jpm

They can be recognized in a type switch as <1ah>, <1bh>, <1ch>, and <1dh>. They are Library Data objects, i.e. a type followed by a 5-nibble size word, followed by the data, and evaluate to themselves.

Oh, yes! They really do exist. Here are two short ASC programs to play with Long Real numbers. "D9D202BA819AF819FF301C5A2B2130496B" ASC\-> 'R\->LR' STO "D9D202BA819AF810DB460B5A2B21304635" ASC\-> 'LR\->R' STO These two routines do type checking, the real heart of them is the routines at 2A5C1 and 2A5B0 (respectively).

Wlodek told me that 2EC11 SYSEVAL converts the number in level 1 to system binary (object type 22). I don't know what use this is, but does anyone know of sysevals to convert to the others? Example: 123 #2EC11h SYSEVAL gives: <7Bh> in hex mode, <123d> in dec mode, <173o> in octal mode, and <1111011b> in binary mode. -- Jeremy |-) Smith smithj@jacobs.cs.orst.edu
