Re: MCH3402 received when calling getHtmlIfsMult

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

Good question, Greg. I ran into that, also, with large spreadsheets. 
These are fairly small HTM files, though. And there weren't many in the 
job until the error occurred. And this user is the only one getting this.

There is a more recent WrtSectionToStmf that gets around that limit - we 
are behind on releases, so I've been using WrtHtmlToStmf() early on, 
then AppHtmlToStmf() occasionally - both are supposed to clear the HTML 
buffer.

Weird stuff!

Thanks
Vern
