Appendix B Sec8
PPLUS is a greatly enhanced replacement to PLOT5. Most PLOT5 syntax and commands are identical to PPLUS usage. However, there are the following differences and incompatabilities.
RDCOM command has been replaced by the @ command.
The LEV command replaces the LEVEL and CLINE commands.
In format statements and labels single quotes (') must be replaced by two single quotes (''). The same applies to double quotes ("). See the chapter on labels.
The LIMITS command is enhanced.
IF / ELSE / ENDIF and WHILE / ENDW logic are available in command files. The INC and DEC commands are available to increment and decrement symbols.
The TXLINT, TXLABP, TXLSZE, TXNMTC and TXTYPE commands should be used instead of using the corresponding arguments in the TAXIS command.
The TIME command should be used instead of the TMIN, TMAX and TSTART commands.
NOTE : The following commands are not supported in this and future versions of PPLUS:
TMIN, TMAX and TSTART
LEVEL and CLINE
RWDSEQ, READSEQ and SKPSEQ
TAXIS will not support the obsolete arguments.
