Passing values from PostScript to the 'outside world'

[Guest_imported]

I have a need (never mind why- it's too complicated to explain!, and is partly academic anyway) to pass a value from PS to the outside world, ie outside of PS. Let's say we a) have a PS interpreter in our PC, and b) have a value on the operand stack- perhaps the result of a calcualation, and I want to utilise that value outside of PS, perhaps as a command line argument to a VB program.

Anyone got any thoughts on that please? Jim Brown,

You can store any data into external file by "write", and "writestring" operators.

Thanks PS prog... that might do the trick. Now, if only
I could remember why I needed to do that . . . . Jim Brown,

Hi Jim - there are file i/o operators of course, where you can write to a file. There is also the "=" and "==" operators, which pass items on the stack to stdout.
