Bruce,
Try this very simple approach to form a command with correct syntax to execute.
SET VAR vTableName TEXT = 'cPOHeader'
SET VAR vString TEXT = ('SELECT ... FROM'&.vTableName)
&vString
See how the variable "vString" is executed.
Have fun!

Gurus and Gurettes:
My greatest coding challenge remains the use of
ampersand variables. I get the concept, but my execution ... hoo boy.
So here's what works:
  SELECT (MIN(cpoDate)) INTO vdateStart INDIC vind1 +
   FROM cpoHeader WHERE (IYR4(cpoDate)) = .vyearStart
But I need to sub-out the table name, and column
name 'cpoDate' with the likes of 'invDate', 'shipDate', etc.Â
This does the trick for the column name:
  SET VAR vcol_date TEXT = 'cpoDate'
  SET VAR vamp_dateCol_min TEXT = '(MIN(&vcol_date))'
  SET VAR vamp_dateCol_iyr4 TEXT = '(IYR4(&vcol_date))'
  SELECT &vamp_dateCol_min INTO vfts_dateStart INDICATOR vind1 +
   FROM cpoHeader WHERE &vamp_dateCol_iyr4 = .vyearStart
... but only so long as the literal tablename
'cpoHeader' is included in the FROM clause.
This returns a syntax error:
  SET VAR vtableName TEXT = 'cpoHeader'
  SELECT ... FROM .vtableName ...
... as does this:
  SET VAR vtableName TEXT = 'cpoHeader'
  SELECT ... FROM &vtableName ...
... as does this:
  SET VAR vtableName TEXT = 'cpoHeader'
  SET VAR vamp_from_tablename TEXT = 'FROM .vtableName'
  SELECT ... &vamp_from_tableName ...
... as does this
  SET VAR vtableName TEXT = 'cpoHeader'
  SET VAR vamp_from_tablename TEXT = 'FROM &vtableName'
  SELECT ... &vamp_from_tableName ...
Clearly, I'm flailing. Any assistance much appreciated!Â
