153.0. "key[0,32]=34; read/key=&key" by SPRITE::OSMAN () Mon Aug 26 1985 14:17
I'm attempting to read the shelf database from a .com file. Here's a
hypothetical code fragment:
$ key = ""
$ key[0,32] = 33
$ read chan /key=&key record
That one works fine. However, this doesn't:
$ key = ""
$ key[0,32] = 34
$ read chan /key=&key record
Why ? Because 34 is ascii for a double quote !
Can anyone think of a hack to get around it ? More specifically, given
a file keyed upon four-character strings, how can a record be read from
dcl whose key contains a double quote mark AND at least one null ?
(If there weren't a null, things like /key="""abc" would win.)
The best I've come up with so far is to read a record NEAR and BEFORE the
desired one, and them home in by reading sequential records (i.e. omit the
/KEY). Anyone have a better idea ?
