This page provides a summary of strings in ZPL. If you find inconsistencies between this document and your use of ZPL, or bugs in user-defined reductions, please let us know at firstname.lastname@example.org.
String variables in ZPL are currently implemented using a static array of 256 characters. String assignment is implemented as a copy from the source string to the destination string.
Comparison between two strings using the standard ZPL
>=) is supported
using C's strcmp() function. In addition, string concatenation is
supported using ZPL's
operators. Other standard string functions are currently
unsupported, either as operators or as library routines, though
the user can prototype the C routines and pass ZPL strings in to
them. Our goal is eventually to support C's standard string
interface in one of these forms. If this lack is holding you up,
please let us know.
