Using verify exit routines z/OS TSO/E Programming Services SA32-0973-00 |

Your Command Processor can provide verify exit routines to perform checking
when the Parse Service Routine encounters either of the following in the command
buffer:
To indicate the presence of a verify exit routine, specify the entry point address of the routine on the VERIFCK= operand in the IKJUNFLD macro instruction. This address must be within the program that invokes the Parse Service Routine. When the Parse Service Routine encounters a keyword operand or subfield operand in the command buffer that is not specifically defined in the PCL, it determines whether a PCE has been created by the IKJUNFLD macro instruction. If parse encounters such a PCE, it gives control to the verify exit routine; if it does not, the operand is treated as not valid. When unidentified keyword operands are present in the command buffer, the Parse Service Routine uses only the first specification of the IKJUNFLD macro instruction. Similarly, when an unidentified keyword is present within a subfield, parse uses only the first specification of the IKJUNFLD macro instruction within a subfield specification. |
