IKJEFLN1 uses the key field conventions described in Table 1. Each parameter may or may not use all the key field settings depending on the field's function. Figure 1 shows the acceptable values of the key field for each of the parameters. The IKJEFLN1 parameter list uses the key field value of X'04'. This value indicates that the field has been validated. After logon processing determines that the field is valid, it sets the key field to X'04' and locks the field to prohibit any additional prompts for data. If IKJEFLN1 validates a field and does not want logon processing to validate the field, it should set the key to X'04'. Some fields must be validated by logon processing even if the exit
sets the key to X'04'. The fields that logon processing
must validate are:
If this exit marks a field as valid that is not valid, logon processing will issue an abend 01A with a reason code of 36. Note: The value in the "Data" column contains actual data or the address
of the actual data depending on the value in the "Key" column. For
a definition of the Key values, see Table 1.
