&MAIINKEY

Indicates the value of the key used to enter data.

Returns the value of the key used to enter data when a data stream is received from the SLU (terminal), as follows:

ATTN: the ATTN key
CLEAR: the CLEAR key
CARD: operator ID card
ENTER: the Enter key
MAG: magnetic card
NONE: no AID generated
PA1 to PA3: Program Attention Key 1 to 3
PF1 to PF24: Program Function Key 1 to 24
REQ: test request
SEL: selector pen attention
SF: inbound structured field
TRIG: trigger action

Example: &MAIINKEY

&IF &MAIINKEY = PF3 &THEN &GOTO .END

Notes:

When used to test the key used to enter data, an &MAIINKEY returns a null value if there is no outstanding data. Data is outstanding from the time an &MAIREAD is satisfied until an &MAICONT, &MAIDEL or another &MAIREAD is issued.

&MAIINKEY is sensitive to the setting of the &CONTROL PFKMAP option.

If &CONTROL PFKMAP is in effect, F3 to F24 are mapped into F1 to F12. For example, receipt of PF13 results in &MAIINKEY being set to a value of PF1.
