Hi Jordan,

You can use the RETURN= specifier to get the size of an axis, and then use
backquotes (``) to evaluate a variable as an argument of the REPEAT
command.  For example, if your variable of interest is called "v":

LET n = `v,RETURN=ksize`
REPEAT/k=1:`n` (...)

or more concisely,

rep/k=1:`v,r=ksize` (...)
