Otherwise, just analyze each of the next characters, adding it to your base string (which should start with the value ""), until you get a character that is NOT a digit. You might use isdigit() for this.

Sort of what I ended up doing, but I like Dragan's solution too.

CLEAR 

m.ModString = "23^^C4~21^^C4~22^^C4~27^^C4"

m.ModCount = OCCURS('~', m.ModString)

m.Mods = ''

FOR ModLoop = 1 TO m.ModCount
	m.Mods = m.Mods + SUBSTR(m.ModString, AT('~', m.ModString, ModLoop) +1, 2)
ENDFOR

? m.Mods
