Syntax: CH_ISMEMO(<fieldC>)

Returns .T. if specified field is a memo field.

Example

DBF structure:      NAME      C 20
                    PHONE     C 15
                    SALARY    N 10
                    REMARKS   M

? CH_ISMEMO("PHONE")
  .F.
? CH_ISMEMO("REMARKS")
  .T.

Notes

This function was created because the Clipper TYPE and VALTYPE functions
actually force Clipper to read the memo field.  This causes unnecessary IO
if all that is needed is to test the field's type.
