4GL Access: RW

The ReadOps attribute specifies the CurOps value to use when the value of the CurMode attribute for a frame is FM_READ.

OpenROAD enforces this attribute whenever the frame's CurMode setting is FM_READ. If you change this attribute when the CurMode attribute is other than FM_READ, it does not take effect until you also change the CurMode setting to FM_READ.

Valid values are:

OP_NONE
OP_APPEND
OP_APPENDINSERT
OP_APPENDDELETE
OP_APPENDINSERTDELETE

Descriptions of system constant values and their numeric equivalents are listed in TableField Operations Settings.

Setting the CurOps attribute can affect the setting of the ReadOps attribute. For information about this relationship, see CurOps Attribute.
