Dear list members, In the Winisis 1.5 manual one can read the following: "Note that, at present, only the following ISIS library routines are available. ASSIGN, CHR, COPYSTR...." (p. 140). But in the manual there is no place to describe the semantics and the syntax of these functions. Do you know any documentation which focuses of the Isis library routines? I Googled a lot, investigate the Unesco's Isis site etc. but i haven't found anything usable. Thanks in advance, Peter Kiraly
