Hello Peter:
CHR$(136) is what you seek. Rather than perform PRINTCHR$(136) on several laptops in order to see if the lower case Greek letter Pi emerges, two pages within the NATIVE manual show all of the character shapes: page 18 for the M100 laptop, and page 19 for the M102 and M200 laptops. The NATIVE manual file (as well as every file of NATIVE) is available for inload at the Club100 Member Upload Library. Follow the path Club100 Member Upload Library/Ron Wiesen/NATIVE/Native.pdf. See page 18 which shows all of the character shapes of the M100 laptop. Character code 136 [i.e., CHR$(136)] produces the character shape of a ! symbol that's been rotated 180 degrees. See page 19 which shows all of the character shapes of the M102 and M200 laptops. Character code 136 [i.e., CHR$(136)] produces the character shape of the lower case Greek letter Pi.

(Big Brother is watching us!) As far as I know, all the M100 that the rest of you guys use, have serial numbers from 1983. Now the question is: did the 2 changes (see above) occur simultaneous? That can only be answered by testing every machine we have and checking production dates. Like I proposed in 2013... OR check out the product number: mine is (I just found the message, see below) 26-3801A, the A stamped.
