For AIPS users who are learning CASA, it is intuitive to think about equivalent tasks between the two software packages. Below are some AIPS-to-CASA equivalent tasks; note that there is not always a one-to-one transformation between the two packages.

|---|---|---|
| BLCAL | Calibrate amplitudes and phases in a baseline-based fashion. | |
| BPASS | BANDPASS | Calibrate bandpasses |
| CALIB | GAINCAL | Calibrate gains (amplitudes and phases) |
| CLCAL | APPLYCAL | Apply calibration to data |
| COMB | IMMATH | Combine images |
| CPASS | BANDPASS | Calibrate bandpasses by polynomial fitting |
| DBCON | CONCAT | Concatenate uv datasets |
| DEFAULT | DEFAULT | Load a task with default parameters |
| FILLM | IMPORTVLA | Import old-format VLA data |
| FITLD | IMPORTUVFITS | Import a uv dataset which is in FITS format |

| QUACK | FLAGDATA | Remove first integrations from scans |
| SETJY | SETJY | Set flux densities for flux cals |
| SMOTH | IMSMOOTH | Smooth an image |
| SNPLT | PLOTCAL | Plot gain calibration tables |
| SPFLG | VIEWER | Flag raster image of time v. channel |
| SPLIT | SPLIT | Write out uv files for individual sources |
| TASK | INP | Load a task with current parameters |
| TGET | TGET | Load a task with parameters last used for that task |
| TVALL | VIEWER | Display image |
| TVFLG | VIEWER | Flag raster image of time v. baseline |
