Yes, I did look at the help.

And, this change results in the ColumnWidths being "0,7,80", which are still
far too small.

Try this small code segment:

LOCAL sColWidths AS String
sColWidths = "0,"

CLEAR
CLOSE DATABASES ALL

CREATE CURSOR Temp1;
 (ID N(4), Caption Character(50))

SELECT Temp1

sFontName = "MS Sans Serif"
iFontSize = 8

FOR iColumn = 1 TO FCOUNT()

	iSize = TXTWIDTH(replicate('O',fsize(FIELD(iColumn))), sFontName, iFontSize)
	
	sColWidths = sColWidths + TRANSFORM(CEILING(iSize)) + ","

ENDFOR

? sColWidths

RETURN
