CA Easytrieve does not currently provide the functionality to add a leading zero in the SYSTIME field.
The following code will insert the leading zero for the SYSTIME field:
WS-TIME W 8 A
FIRST-PART WS-TIME 1 A
JOB INPUT NULL
WS-TIME = SYSTIME
IF FIRST-PART = ' '
FIRST-PART = '0'
DISPLAY 'EDITED SYSTIME = ' WS-TIME
