TCLCK(PRSIEN,S1,E1,S2,E2,PPLCK,PPLCKE) ; Time Card Lock for Date Range Change
 ; This API attempts to lock employee timecards for pay periods that
 ; are impacted by a change to a date range.  Only existing pay periods
 ; that are covered by a PTP memo will be locked.
 ;
 ; Input
 ;   PRSIEN   - Employee IEN (file 450)
 ;   S1       - Old Start Date (FileMan internal)
 ;   E1       - Old End Date (Fileman internal)
 ;   S2       - New Start Date (FileMan internal)
 ;   E2       - New End Date (Fileman internal)
 ;   PPLCK()  - Array of Locked Pay Periods passed by reference
 ;   PPLCKE() - Array of Pay Periods with Lock Error passed by reference
 ;   Note that both these arrays are initialized by this API.
 ; Output
 ;   PPLCK()  - Array of Locked Pay Periods may be updated
 ;              format PPLCK(pay period IEN file 458)=""
 ;   PPLCKE() - Array of Pay Periods with Lock Error may be updated
