| COLΣ | Command |
Type: | |
Description: | Column Sigma Command: Specifies the |
| the current statistics matrix (the reserved variable ΣDAT). |
| COLΣ combines the functionality of XCOL and YCOL. The |
| number xxcol is stored as the first parameter in the reserved variable ΣPAR (the default is 1). The |
| |
| ΣPAR (the default is 2). |
| COLΣ accepts and stores noninteger values, but subsequent commands that use these two |
| parameters in ΣPAR will cause errors. |
Access: | …µCOLΣ |
