Variable on Master Pages.....getting them to talk

[Eduardo F. Cidade, Sr.]

Good evening all

Here's what I'm trying to accomplish:

Standard Frame 7.2....WXP is the environment

Master page...trying to create a variable which will amplify the page
number sequencing

Here's what the numbering looks like now:

2H-2 (this is actually page 1 because it follows another document, so
the numbering follows the preceding document)

............

Here's what I want the page numbering to look like but don't know how:

2H-2A (there are reasons for wanting this....too many and it involves
trying to steer away from disconnected pages)

Followed by....

2H-2B
2H-2C

.....and so on

Is there a way to add such a variable to the master page?  I know there
must be.

Thinking caps on....phasers on stun.....warp speed Mr. Sulu!

Thanks to all

Eduardo
