Subject:      monthly update

An interesting question posted somewhere else. It goes, in part:

"I've got a data table with text variables named m0, m1 up to m62. Each month
this dataset is updated, with the latest month's data stored in m0 while all
the rest need to move up on index, i.e. m0 should be renamed m1, m1 should be
renamed m2, etc. up to m62 which should be renamed m63."
