Hi Gerry.
Here's how I use the emulator for program testing and debugging:
1. use a text editor (Notepad is more than enough) to write the program; please remember to use the "usual" conventions for the digraphs, i.e.:
Num Sym Description
--- --- -----------
128 \<) angle symbol
131 \v/ square root
132 \.S integral symbol
133 \GS Greek Sigma (\GSLIST)
135 \pi pi
136 \.d derivative symbol
137 \<= less or equal
138 \>= greater or equal
139 \=/ unequal
141 \-> right arrow (\->LIST, \-> a b c)
142 \<- left arrow (\<-local)
143 \|v down arrow (\|vMATCH)
144 \|^ up arrow (\|^MATCH)
156 \PI capital pi (\PILIST)
159 \oo infinity
171 \<< program delimiters
187 \>>
092 \\ backslash
2. select the listing you typed
3. copy it
4. go to the emulator and select the menu item "Edit" ---> "Paste stack"
5. with the object on the 1st stack level, run the following "translation" program (by John H. Meyers) that you should have already typed in and saved in a variable of your choice (say "IN" ?):
\<< \->STR 3 TRANSIO RCLF SIZE 3 < #3016Bh #2F34Dh IFTE SYSEVAL + STR\-> \>>
6. save the "translated" object into a variable
7. run it and you're done
The above has the advantage, IMHO, to be a fairly straightforward testing process, which you can repeat "ad libitum" until you're happy with your program and get it "settled" to your real 50G :-)
Hope this helps.
Best regards.

P.S.: as far as searching the MoHPC archives goes, I use Google advanced search, specifying "www.hpmuseum.org" in the "Domain" field of the search...
