Restrictions

SDF-CONV cannot convert all ISP commands and old SDF commands and their operands into SDF commands with corresponding operands. Certain commands, operands and operand configurations are excluded from conversion right from the start. Moreover, there are certain so-called "conditional conversions" which are dependent on the operating system version. The conversion of procedure parameters as operands can also be subject to restrictions, as well as the conversion of non-S procedures into S procedures.
The command records concerned are transferred unchanged to the output procedure (SDF-CONV outputs an error message to SYSLST) or, if the condition regarding version dependency was fulfilled, are converted.
