string manipulating method

[cckp]

with iPXE scripting how to calclulate string length? do a substr?

currently I can only do some very simple things, like get left 4 letters, get right 1 letter(from left 4 letters), get right 2 letters(from left 4 letters), by type casting



P.S.

RE: Trim whitespaces from a string?
String manipulation functions have not been implemented
as we're still discussing how they should be provided to the end-user (API).
