Hi guys,

I wanted to write a tiny procedure which prints a variable name and
the value and a newline, the c equivalent would be a macro along the
lines - #define PRINT_DOUBLE(x) printf(#x "= %f\n", x)
but I don't know how to overcome pass - by - value.

Ideal functionality:

testVar = 1
my_print, testVar

testVar = 10
IDL>

Any suggestions?

Many thanks,

Daniel
