I'm working on a project that receives an array of data that looks like
this (example):
@fieldspecs = qw
(
JobNum 14
ProjectID 25
PartNum2 50
ProdQty13 15.2
);
The array is a definition of fields in a file; the fieldname followed by
the field width. The fieldname frequently contains digits. When I get
the data, it is text so I put it in an array (like you see above)
because it is important to reference the fieldnames in the order I
receive them. The array ALWAYS has a fieldname followed by the width,
the the number of elements is always divisible by two.
However, I also want to access the data as a hash so that for a given
fieldname I can easily grab the width.
It is easy enough to convert this array to a hash, but...
...is there a Perl-ish way to either ram the *fieldnames only* into a
new array, OR, delete the field widths from the array leaving only the
fieldnames??
