.pop [-p] <register_name> [+][<relative_pathname>|-] .pop [-p] <register_name> [>|>>]<register_name>
Write the contents of a register to a file, to the step log, or to another register.
The optional -p parameter makes the command refer to a project register. Project registers are separate from ordinary registers, and project registers persist after a job ends.
Use uppercase to create register names and to reference all register types. Even though you can create registers using lowercase letters, registers are stored and must be referenced using uppercase letters.
The following examples show the variety of uses for a .pop command:
.pop A data.txt - writes register A to the file data.txt, located in the step's working directory.
.pop VER +data.txt - appends the contents of register VER to the file data.txt.
.pop ALPHA - writes the contents of register ALPHA to the step's log.
.pop ALPHA > BETA - gives register BETA the same contents as register ALPHA.
.pop A >> B - appends the contents of register A to register B.
