Program macros process edit commands by using the ISPLINK or ISPEXEC interface. ISPLNK and ISPEX are the interface names used in FORTRAN and Pascal programs. Parameters are passed to the ISREDIT service as follows:

• CALL ISPLINK ('ISREDIT',length,buffer)

  CALL ISPEXEC (length,'ISREDIT command')

where these definitions apply:

'ISREDIT'

The service name.

length

A fullword number indicating the length of the command buffer. When a zero length is passed, the maximum buffer length is 255 bytes.

buffer

Can contain any edit command that is valid from a macro, typed with the same syntax used in a CLIST or REXX exec.

command

Any PDF edit command that is valid from a macro, typed with the same syntax used in a CLIST or REXX exec.
