usage: prcodes = {…; position dependent command sequences }

PRCODES is a list of printer control strings used by the PRINT command. Each string in PRCODES is associated with a particular printer function. Configuring CIGAL to recognize a new printer involves loading the appropriate control sequences for that printer into PRCODES.

The meaning of the strings within PRCODES is position dependent. Some command strings expect arguments, which will be provided at execution time. The special characters '\001' and '\002' are used to indicate where in the command string the argument should be inserted; \001 and \002 will be replaced by the first and second arguments, respectively. The following table describes the function associated with each string:
