M Modify CFS Memory Area

M L'addr', C'string' | X'string'

This command can be used to modify the standard values for the currently loaded CFS program. The Modify command is a substitute for the IDA command, /M C'...' INTO L'...', that could be called from TSOS by a single user. The Modify command should only be used to amend CFS-internal parameters which have no specific CFS modification command.

L'addr' Address of the location to be modified in the loaded program. The parameter addresses can be ascertained using the CFSMAIN source program. For example, the Assembler command MVI 33(R1),C'Y' corresponds to M L'1021',C'Y' (L'1021' = L'1000' + 33) in CFS Modify syntax. All CFS-internal parameter addresses in CFSMAIN will be maintained in future versions of CFS.

C'string' | X'string' The content to be copied to the specified address.

Examples:

M L'1031',X'00'

The contents of the memory location L'1031' will be reset to X'00' as a result of this statement. This will result in no lower case to upper case conversion taking place when capturing a CFS mask using the Hardcopy function.

M L'12E5',C'CFS.JRSAVE.name '

The character string 'CFS.JRSAVE.name___' will be written to memory as from address L'12E5'. This will change the default JRSAVE file name, for example for a second user.
