Re: String operation

[rasnitsyn@xxxx]

Hi Tomasz!

Great! Thank you very much. What a nice Idea to use a function 
returning a number!

I absolutely agree with saving on redundand "Write()". 
How about eliminating WriteVal () as well? A numeric variable, or the 
current element of an array variable can be automaticaly converted to 
a string if it appears in context of a string operation. WriteVal() 
will be still required if a number/vector is the first item to be 
printed. (This is JAVA concept of automatical call of toString()).
Examples:
" myvalue = " + myvalue; // the same as " myvalue = " + writeval 
(myvalue);
but 
WriteVal (myvalue) + " is myvalue" ; // Writeval is required here.

Thanks,
Dima.
