STRING64 doc carries this warning:
it will produce assembly errors in the following situations:
a. STRING is used in more than one CSECT in the same assembly
An alternative, which does not have this restriction, is found as the STRMAKE
macro, part of the SYSMACS member of CBT file 669.

CBT file 321 (COBANALZ) also has an updated version of the STRING macro named
STRING64 with supporting code that is very useful. Browse the source of
COBANALZ (or better an assembly listing) to see it in action.

There is a very useful macro on the CBTTAPE called STRING.
You can do something like
STRING 'something ',(fielda,,T),' something else ',(0(R1),6,T),' Register 1
=',((R1),,X),INTO=somefield
the STRING macro automatically puts the length of the string it builds into the
SOMEFIELD in register 15 so you can STH R15 intop the first two bytes of the
WTO field.
the above assumes that fielda is a text field of some length, (the ",,T" tells
it to truncate ending blanks), and in this case R1 points to some other field
of undetermined length that you want the first 6 bytes of (only up to the first
blank field in those 6 bytes), and R1 is printed out in 8 hex characters.
The SHOWZOS command makes a lot of use of this macro, (also avaialable on the
CBTTAPE)
It's very useful in instances where you have a lot of variables of different
formats that you need to move around or generate messages from.
