Re: IsAstack ( )

[Klaus Major]

Hi Hugh,

I need a robust alternative to "if there is  a stack pFilePath"  
that does
*not* load the file into memory and potentially  cause problems  
with shared stack
name space.

Can anyone improve or see  anything not foolproof with this?

function isAstack  pFilePath
return line 1 of  url("file:"&pFilePath)="#!/bin/sh"
end isAstack

In the latest fileformat 2.7x, the first 8 bytes of a valid stackfile  
are:

REVO2700

So I would use a combination of checking the suffix and reading/ 
checking the first
lines/chars of the actual stackfile.

/H
