[Coco] Error in BASIC manual. ?

[michaelkline704 at gmail.com]

Ok, I have the answer: 
30  HLINE(22,33)-(100,90) ,3,BF should be 30  HLINE(22,33 )-(100,90) ,PSET,BF
The number 3 should be either PSET or PRESET. Look at the programme example on page 175 regarding HGET. It shows the correct syntax for HLINE. So yes, there is a typo in the manual.

Could the spaces be a problem?
Indicated with a *.

30 *HLINE*(22,33*)-(100,90)*,3,BF

30 HLINE(22,33)-(100,90),3,BF
