character search

[ken gray]

i just cant figure out how to make this work.
what am i missing?

Code:

Copy      Help

str a b
a="1234"
b.left(a 1)
if b="0-9"
,out b

[Gintaras]

if(isdigit(a[0]))

[ken gray]

what am i doing wrong here?

Code:

Copy      Help

str a b
a="123"
b.left(a 1)
z=findrx(b "(\d)")
if z>0
,out b

[Gintaras]

findrx, like other find functions, returns -1 if not found, because index of first character is 0.

if z>=0
